Report of the Double-Molybdate Phase Cs2Ba(MoO4)2with a Palmierite Structure and Its Thermodynamic Characterization

The existence of a novel double-molybdate phase with a palmierite-type structure, Cs2Ba(MoO4)2, is revealed in this work, and its structural properties at room temperature have been characterized in detail using X-ray and neutron diffraction measurements. In addition, its thermal stability and thermal expansion are investigated in the temperature range 298-673 K using high-temperature X-ray diffraction, leading to the volumetric thermal expansion coefficient αV ≈ 43.0 × 10-6 K-1. The compound's standard enthalpy of formation at 298.15 K has been obtained using solution calorimetry, which yielded ΔfHm°(Cs2Ba(MoO4)2, cr, 298.15 K) = -3066.6 ± 3.1 kJ· mol-1, and its standard entropy at 298.15 K has been derived from low-temperature (2.1-294.3 K) thermal-relaxation calorimetry as Sm°(Cs2Ba(MoO4)2, cr, 298.15 K) = 381.2 ± 11.8 J K-1 mol-1.

Synthesis, crystal structure and TEM study of the new hollandite-type Ba～8/7Mo8O16

Investigation of the Cs-Ba-Mo-O system by fused salt electrolysis at 960°C has led to the new related-hollandite compound Ba～8/7Mo8O16. Single-crystals of Ba～8/7Mo8O16 were examined by electron diffraction and high-resolution electron microscopy. Ba～8/7Mo8O16 was found to present a tetragonal I basic unit-cell (a=10.21 A?, c=2.89 A?) with a one-dimensional modulation of wavevector q close to 4/7 along c* at room temperature. Refinement of the crystal structure was made on X-ray single crystal data in the seven-fold supercell in the three-dimensional space group I4 (a=10.214(2) A?, c=20.255(5) A?, Rw(F2)=0.0844 for all 7767 independent reflections and 149 parameters). In the latter supercell approach, the Mo atoms in the double edge-sharing rutile-type chains form Mo3 triangles and planar rhomboidal Mo4 clusters that coexist in equal proportions. The Mo-Mo distances vary from 2.5341(8) to 2.696(2) A? and from 2.5341(8) to 2.894(4) A? in the Mo3 and Mo4 clusters, respectively. The shortest intercluster distance is 3.047(4) A?. The Mo-O distances range between 1.81(1) to 2.418(8) A? as usually observed in reduced molybdenum oxides. The Ba2+ cations occupy the large square channels in square prismatic environment of oxygen atoms with the distribution sequence ...Ba-□-Ba-Ba-□Ba-□-....

HEATS OF FORMATION OF SOME SODIUM AND BARIUM VANADATES AND MOLYBDATES.

An isoperibol room-temperature calorimeter has been constructed to measure the spontaneous reactions of BaO and Na//2O with MoO//3 and V//2O//5 after ignition. With this calorimeter, the heats of formation from the component oxides have been determined fo

Formation of periodic precipitation patterns: A moving boundary problem

A new scenario for the formation of Liesegang patterns is proposed. The periodic precipitation pattern formation in a gel column is interpreted as a moving boundary problem. The existing time law, space law, and width law are revisited and reformulated on the basis of a moving boundary assumption and more meaningful explanations are given. All the new equations suggested were found to be in good agreement with experimental observations.

Novel carbon and sulfur-tolerant anode material FeNi3?PrBa(Fe,Ni)1.9Mo0.1O5+:δ for intermediate temperature solid oxide fuel cells

Suppression of carbon deposition and sulfur poisoning without sacrificing electrochemical performance is crucial for operating solid oxide fuel cells (SOFCs), especially at intermediate temperatures (IT). In this work, nickel-doped A-site deficient perovskite oxides (PrBa)0.95Fe1.9-xNixMo0.1O6-δ (PBFMNix, x = 0, 0.1, 0.2, 0.3, 0.4) were synthesized and investigated as potential anodes for IT-SOFCs. With increased amounts of Ni2+, the ratios of Fe2+/Fe3+ and Mo5+/Mo6+ in as-prepared PBFMNix continuously decreased under a charge-compensating mechanism, which simultaneously depressed the formation of the impurity phase (BaMoO4). Interestingly, the substitution of Ni2+ benefits the reduction of Fe3+ to Fe2+ and Mo6+ to Mo5+, and small portions of Fe and Ni elements are exsolved from the parent oxides, forming FeNi3 alloy nano-particles that greatly accelerate the chemical adsorption and surface reaction kinetics of H2, and thus improve the electrochemical performances of oxide-based anodes. Transformation of the electrical conduction from p-type to n-type after reduction was also observed. A very small polarization resistance of 0.028 Ω cm2 at 750 °C was achieved for the cell with the PBFMNi0.3 anode. Importantly, fueled with syngas with 50 ppm H2S, the maximum power density of a button cell based on the PBFMNi0.3 anode and an Sm0.2Ce0.8O1.9 (SDC) electrolyte-supporting configuration can reach 498 mW cm-2 at 750 °C, and long-term stability over 100 hours can be demonstrated with negligible performance decay. All these results indicate that PBFMNi0.3 is a promising high-performance anode material with good coking resistance and sulfur tolerance in intermediate temperatures.

Order and Disorder: Toward the Thermodynamically Stable α-BaMoO2F4from the Metastable Polymorph

A fully ordered noncentrosymmetric barium molybdenum oxyfluoride, α-BaMoO2F4, has been synthesized by a hydrothermal reaction at 200 °C in a concentrated hydrofluoric acid solution. A centrosymmetric polymorph with O/F disorder, β-BaMoO2F4, has been obtained in several minutes when the reaction mixture was stirred at room temperature in the same medium. Interestingly, we found that the metastable β-BaMoO2F4 transforms into the thermodynamically stable α-BaMoO2F4 in an ambient condition. More detailed kinetic studies using powder X-ray diffraction indicate that the MoO2F4 octahedra in the kinetic phase, β-BaMoO2F4, rearrange through the constant dissolution/precipitation process to find a more stable orientation and form the fully ordered α-BaMoO2F4. Density functional theory (DFT) calculations suggest that the formation of the thermodynamically stable α-BaMoO2F4 is driven by the strong Mo-O π-interactions induced by Ba2+ cations. The new finding on the understanding of the kinetics of solid-state reactions suggests a novel way toward an effective discovery of functional materials with asymmetric structures.

Erbium-Doped Upconversion Phosphor in the Li2MoO4–BaMoO4–Y2(MoO4)3 System

Abstract—: We have investigated subsolidus phase equilibria in the Li2MoO4–BaMoO4–Y2(MoO4)3 system and constructed its phase compatibility diagram. A ternary molybdate with the composition Li3Ba2Y3(MoO4)8 and a monoclinic scheelite-like structure (sp. gr. C2/c) has been identified on the BaMoO4–LiY(MoO4)3 join. Doping Li3Ba2Y3(MoO4)8 with Er3+ ions, we obtained a Li3Ba2Y2.85Er0.15(MoO4)8 upconversion phosphor possessing efficient anti-Stokes luminescence in the range 530–850 nm under IR excitation (λex = 977 nm). The synthesized phosphor has been characterized by X-ray diffraction, differential thermal analysis, and IR spectroscopy.

Magnetic and structural studies of the double perovskites Ba 2REMoO6

A magnetic, electronic and structural study of the double perovskites Ba2REMoO6 (RE=Sm, Eu, Gd, Dy) has been performed. All materials crystallise in the cubic Fm3?m symmetry space group and the cell volume decreases as RE varies from Sm to Dy in accordance with Vegard's law. An antiferromagnetic transition is observed below TN=130 and 112 K for RE=Sm and Eu, respectively. The Néel temperatures of these ordered rare earth molybdenum double perovskites are much higher than previously observed in double perovskites containing Eu or Sm and a 4d or 5d transition metal arranged in an ordered rock salt configuration. The high Néel temperatures arise due to a strong superexchange magnetic interaction via the Mo-O-RE-O-Mo pathway. All of the phases are electronically insulating and there is no evidence of magnetoresistance at any temperature.

Solvothermal morphology studies: Alkali and alkaline earth molybdates

A convenient and systematic solvothermal pathway towards alkali and alkaline-earth molybdates has been established. The solvothermal treatment of a molybdenum-based precursor material (yellow molybdic acid, MoO 3·2H2O) with ionic additives (alkali or alkaline-earth halides) provides access to a spectrum of molybdates. Their particle morphology can further be addressed by optimizing the reaction conditions. The resulting products cover a wide scope of sizes and morphologies, ranging from molybdenum oxide fibres with high aspect ratios and nanoscale diameters to millimeter-sized crystals of novel alkali molybdates. Both anionic and cationic additives exhibit certain synthetic profiles that offer the perspective of turning this approach into a 'toolbox' for the tailoring of molybdate-based materials.

Microwave-assisted synthesis of barium molybdate by a citrate complex method and oriented aggregation

BaMoO4 powders, which have scheelite type structure, were successfully synthesized at low temperatures by a modified citrate complex method assisted by microwave irradiation. The citrate complex precursors were heat-treated at temperatures from 300 to 500 °C for 3 h. Crystallization of the BaMoO4 powders were detected at 350 °C, and completed at a temperature of 400 °C. TEM image of the BaMoO4 product obtained above 400 °C revealed spindle-rods-like or flake-like morphology. The anisotropic growth habit of BaMoO4 leads to the oriented aggregation, which is attributed to the high chemical potentials of the intrinsic structure of BaMoO4. The BaMoO4 powder prepared at 500 °C showed the strongest photoluminescent intensity.

BaMoO4 powders processed in domestic microwave-hydrothermal: Synthesis, characterization and photoluminescence at room temperature

In this paper, BaMoO4 powders were prepared by the coprecipitation method and processed in a domestic microwave-hydrothermal. The obtained powders were characterized by X-ray diffraction (XRD), Fourier transform Raman (FT-Raman) spectroscopy, ultraviolet-visible (UV-vis) absorption spectroscopy and photoluminescence (PL) measurements. The morphology of these powders were investigated by scanning electron microscopy (SEM). SEM micrographs showed that the BaMoO4 powders present a polydisperse particle size distribution. XRD and FT-Raman analyses revealed that the BaMoO4 powders are free of secondary phases and crystallize in a tetragonal structure. UV-vis was employed to determine the optical band gap of this material. PL measurements at room temperature exhibited a maximum emission around 542 nm (green emission) when excited with 488 nm wavelength. This PL behavior was attributed to the existence of intrinsic distortions into the [MoO4] tetrahedron groups in the lattice.

Microwave and infrared dielectric response of temperature stable (1-x) BaMoO 4-x TiO 2 composite ceramics

The (1-x)BaMoO4-xTiO2 (x = 0.0, 0.2, 0.3, 0.338, 0.4, 0.5, 0.66) ceramics were synthesized by the conventional mixed-oxide process. The sintering behaviors, phase composition, chemical compatibility with silver, and microwave dielectric properties of pure (1-x)BaMoO4-xTiO 2 ceramics and 0.662BaMoO4-0.338TiO2 ceramic with H3BO3-CuO addition were studied. Infrared reflectivity spectra of (1-x)BaMoO4-xTiO2 (0.2 ≤ x a;circ 0.4) composites were measured in the range of 50-4500 cm-1 at room temperature. X-ray diffraction analysis reveals that scheelite BaMoO 4 and rutile TiO2 phase coexist with each other at 1275°C and both of them do not react with silver (Ag) at 850°C. When the mole fraction of TiO2 (x value) is 0.4, a temperature stable microwave dielectric material is obtained, with εr = 13.8, Q × f = 40 500 GHz (f = 8.02 G), and τf = -6.13 ppm/°C. Complex dielectric spectra gained from the infrared spectra were extrapolated down to microwave range, and they were in good agreement with the measured microwave permittivity and dielectric losses. With 5 wt% H3BO 3 and 1 wt% CuO addition, the 0.662BaMoO4-0.338TiO 2 ceramics can be sintered well below 900°C, and possess good microwave dielectric properties with εr = 14, Q × f = 48 360 GHz, and τf = +13.9 ppm/°C.

Simultaneous presence of (Si3O10)8- and (Si2O7)6- groups in new synthetic mixed sorosilicates: BaY4(Si2O7)(Si3O 10) and isotypic compounds, studied by single-crystal X-ray diffraction, Raman spectroscopy and DFT calculations

Three new, isotypic silicate compounds, BaY4(Si 2O7)(Si3O10), SrYb 4(Si2O7)(Si3O10) and SrSc4(Si2O7)(Si3O10), were synthesized using high-temperature flux growth techniques, and their crystal structures were solved from single-crystal X-ray intensity data: monoclinic, P21/m, with a=5.532(1)/5.469(1)/5.278(1), b=19.734(4)/19.447(4)/19.221(4), c=6.868(1)/6.785(1)/6.562(1) A, β=106.53(3)/106.20(3)/106.50(3), V=718.8(2)/693.0(2)/638.3(2) A3, R(F)=0.0225/0.0204/0.0270, respectively. The topology of the novel structure type contains isolated horseshoe-shaped Si3O 10 groups (Si-Si-Si=93.15-95.98), Si2O7 groups (Si-Obridge-Si=180, symmetry-restricted) and edge-sharing M(1)O 6 and M(2)O6 octahedra. Single-crystal Raman spectra of the title compounds were measured and compared with Raman spectroscopic data of chemically and topologically related disilicates and trisilicates, including BaY2(Si3O10) and SrY2(Si 3O10). The band assignments are supported by additional theoretical calculation of Raman vibrations by DFT methods.

Magnetic and magneto-transport properties of (Ba0.8 Sr0.2)2 - x Ndx FeMoO6

An investigation of the optical properties and water splitting potential of the coloured metallic perovskites Sr1?xBaxMoO3

The solid solution Sr1?xBaxMoO3 (x=0.00, 0.025, 0.050, 0.075, 0.100 and 1.00) has been synthesised. Rietveld refinement of X-ray diffraction data shows that all materials crystallise with cubic (Pm-3m) symmetry and that a miscibility gap exists from x=0.1–1.0. The optical properties of the metallic perovskites Sr1?xBaxMoO3 have been investigated by a combination of UV–vis spectroscopy and density functional theory (DFT). Upon increasing x from 0 to 1 in Sr1?xBaxMoO3 there is a reduction in the measured band gap from 2.20?eV to 2.07?eV. The measured band gap is attributed to the electronic transition from the Mo 4d t2g band to the eg band. The potential of SrMoO3 and BaMoO3 as water-splitting photocatalysts was explored but there was no evidence of hydrogen or oxygen evolution, even with the presence of a Pt co-catalyst.

Room-temperature preparation of BaMoO4 nano-oetahedra by mieroemulsion method

Electrical conductivity and thermal expansion behavior of MMoO4 (M = Ca, Sr and Ba)

Influence of the cation size on the framework structures and space group centricities in AMo2O5(SeO3)2 (A = Sr, Pb, and Ba)

Two new quaternary mixed-metal selenites, SrMo2O 5(SeO3)2 and PbMo2O 5(SeO3)2, have been synthesized as crystals and pure polycrystalline phases by standard solid-state reactions using SrMoO 4, PbO, MoO3, and SeO2 as reagents. The crystal structures of the reported materials have been determined by single-crystal X-ray diffraction. SrMo2O5(SeO3)2 and PbMo2O5(SeO3)2 are isostructural and crystallized in the triclinic centrosymmetric space group P1 (No. 2). The reported materials exhibit chain structures consisting of MoO6 octahedra and asymmetric SeO3 polyhedra. Complete characterizations including IR spectroscopy and thermal analyses for the compounds are also presented, as are dipole moment calculations. In addition, the powder second-harmonic-generating (SHG) properties of noncentrosymmetric polar BaMo2O5(SeO3)2 have been measured using 1064 nm radiation. Through powder SHG measurement, we are able to determine that BaMo2O5(SeO3)2 has a SHG efficiency of approximately 80 times that of α-SiO2. Additional SHG measurements reveal that the material is phase-matchable (type 1). A detailed cation size effect on the symmetry and framework structure is discussed.

Fabrication of AMoO4 (A = Ba, Sr) film on Mo substrate by solution reaction assisted ball-rotation

Alkaline earth molybdates, such as BaMoO4 and SrMoO4, films have been successfully fabricated on a Mo metal substrate in AOH (A = Ba, Sr) solutions by a ball-rotation-assisted solution reaction, at room temperature. The dissolution of Mo was mainly controlled by the concentration of the H2O2 oxidizing agent and ball-rotation to form MoO42- in the solution. AMoO4 was deposited on the substrate by the reaction between MoO42- and A2+ ions without any high energy or high-temperature treatment. Also, the mass transport of alkaline earth ions onto the solid/solution interface was improved as a result of the vigorous solution agitation by the ball-rotation. Therefore, the rate of deposition of the AMoO4 films was accelerated by the ball-rotation. A decrease in the grain size of the film was observed with an excessive ball-rotation.

Preparation, characterization and electrical conductivity studies of nanocrystalline la doped BaMoO4

Different compositions of scheelite type nanocrystalline La doped BaMoO4 [Ba1-xLaxMoO4+x/2, where x = 0, 0.1, 0.2, 0.3, 0.4 and 0.5] samples were prepared by acrylamide assisted sol-gel combustion process. Dried gels prepared at 60 °C were heated at different temperatures and characterized using TG/DTA, XRD, FTIR and SEM-EDX techniques. From XRD patterns, crystalline phases for La doped BaMoO4 samples were confirmed and their average crystallite sizes were calculated using Scherrer's formula and it was found to be less than 80 nm. Structure and thermal behavior of scheelite type nanocrystalline La doped BaMoO4 samples were identified respectively using FTIR and TG/DTA measurements. Microstructure and existence of O, La, Ba and Mo elements in the La doped BaMoO4 samples were obtained from SEM-EDX and HRTEMtechniques. The 'd' spacing values were obtained for different (h k l) planes and were well matched with the standard BaMoO4. (h k l) values for different directions of planes were assigned for the observed HRTEM images and were matched with standard BaMoO4. Grain and grain boundary conductivities were evaluated by analyzing the impedance data, using the Winfit software, measured at different temperatures.

Structural disorder in AMoO4 (A = Ca, Sr, Ba) scheelite nanocrystals

The crystal structure of sub-15 nm AMoO4 (A = Ca, Sr, Ba) scheelite nanocrystals has been investigated using a dual-space approach that combines Rietveld and pair distribution function (PDF) analysis of synchrotron X-ray diffraction data. Rietveld analysis yields an average crystal structure in which the Mo-O bond distance exhibits an anomalously large contraction (2.8%) upon chemical substitution of Ba2+ for Ca2+. Such a dependence on chemical composition contradicts the well-known rigid character of MoVI-O bonds and the resulting rigidity of MoO4 tetrahedra in scheelites. Unlike Rietveld, PDF analysis yields a local crystal structure in which the Mo-O bond distance shows a negligible contraction (0.4%) upon going from Ba2+ to Ca2+ and, therefore, appears independent of the chemical composition. Analysis of the anisotropic displacement parameters of the oxygen atom reveals that the disagreement between the average and local structural models arises from the presence of static orientational disorder of the MoO4 tetrahedra. Rietveld analysis averages the random rotations of the MoO4 tetrahedra across the scheelite lattice yielding an apparent Mo-O bond distance that is shorter than the true bond distance. In contrast, PDF analysis demonstrates that the structural integrity of the MoO4 tetrahedra remains unchanged upon chemical substitution of the alkaline-earth cation, and that their orientational disorder is accommodated through geometric distortions of the AO8 dodecahedra.

Tm3+ doped barium molybdate: A potential long-lasting blue phosphor

Molybdates have applications in various fields such as phosphors, optical fibers, scintillators, magnets, sensors and catalysts. Thulium ion is an excellent blue activator and plays an important role in the design of persistent luminescent materials. This paper reports the investigation of the structural and luminescent properties of Barium Thulium Molybdate (Ba1?xTmx)MoO4 microcrystals (with x = 0, 0.01 or 0.03). The scheelite-type crystalline structure was identified from XRD and Raman studies. Under ultraviolet (359 nm) excitation, photoluminescence (PL) spectra present the characteristic emission bands at 453 nm and 545 nm which are due to the D12→F34 and D12→H34,5 transitions, respectively, from Tm3+ ions. Thermoluminescence (TL) measurements were performed with powdered samples previously irradiated with beta radiation. The depth of traps, associated with trap levels located inside the band-gap, was determined from TL data using different methods of glow curve analysis. The kinetic parameters, determined from thermoluminescent glow curves, provide evidence about a possible persistent luminescence emission from the (Ba0.97Tm0.03)MoO4 sample. This is a potential blue-light or ultraviolet long-lasting phosphor, with a trapping level lifetime, at room-temperature (300 K), of about 6 days.

Bimetallic BaMoO4 nanoparticles for the C-S cross-coupling of thiols with haloarenes

We disclosed new bimetallic BaMoO4 nanoparticles for the C-S cross-coupling reaction. The C-S cross-coupling reaction of alkyl/aryl thiols with haloarenes was accomplished with high yields. The reaction has good functional group tolerance and selectivity. This is an efficient protocol for synthesizing the building blocks of pharmaceuticals containing C-S bonds. The catalyst is recyclable. The unactivated bromo- and 4-acetyl fluoro-arenes can well couple to afford thioethers in high yields. The reaction is believed to proceed by oxidative addition and reductive elimination.
