Thermal behaviour of some metal complexes of N,N-diethyl-N′-benzoyl thiourea

The thermal behaviour of the complexes of N,N-diethyl-N′-benzoylthiourea (DEBT) with Ni(II), Cu(II), Pt(II), Pd(II) and Ru(III) was studied using differential thermal analysis (DTA) and thermogravimetry (TG). These complexes undergo only a pyrolytic decomposition process. A gas chromatography-mass spectrometry combined system was used for the verification of the first decomposition product and X-ray diffraction method for the characterization of the final products of pyrolysis.

Spatial separation of dual-cocatalysts on one-dimensional semiconductors for photocatalytic hydrogen production

Light-driven hydrogen production using semiconductor photocatalysts has gained much interest owing to their ability to store sunlight in the form of portable chemical fuel. The spatial separation of dual-cocatalysts onto different surfaces has been considered as a useful strategy for fabricating dynamic particulate photocatalysts to hinder charge recombination and reverse reactions. Herein, using one-dimensional (1D) semiconductors, CdSe nanorods as an example, we experimentally demonstrated that photogenerated electrons and holes can be effectively separated along different directions of a 1D semiconductor. Following this phenomenon, the reduction cocatalyst Pt and oxidation cocatalyst PdS were spatially deposited on different sites via an in situ photodeposition process, which drastically enhanced the photocatalytic activity for hydrogen production to more than 20 times, thus exhibiting an extremely high apparent quantum efficiency (AQE) of ～45% at 420 nm. Further studies using photoluminescence spectroscopy indicated that the spatially separated dual-cocatalysts efficiently captured the photogenerated electrons and holes migrating to the surface, which greatly decreased the recombination of charge carriers and consequently led to superior photocatalytic performances. Our work provides an effective strategy for the rational construction of highly efficient photocatalyst systems based on (quasi) 1D semiconductors for artificial solar energy conversion.

Enthalpies of formation of BaPdS2 and LaPd3S4

The BaPdS2 mixed palladium sulfide has been synthesized by direct reaction of a stoichiometric mixture of the PdS and BaS binary constituent sulfides. The standard molar enthalpies of formation of BaPdS2 and LaPd3S4 mixed sulfides were determined by the method of direct reaction calorimetry through synthesizing the respective compounds in a calorimetric cell from the stoichiometric mixture of appropriate starting materials. Combining the experimental results with the reference data for the starting materials, we found Δf,298H0m(BaPdS 2)=-515.4±16.8 kJ mol-1; and Δf,298H0m(LaPd3S 4)=-817.6±43.8 kJ mol-1.

Thermoelectric properties of polycrystalline palladium sulfide

Measurement of the electrical, thermal, and structural properties of palladium sulfide (PdS) has been conducted in order to investigate its thermoelectric performance. A tetragonal structure with the space group P42/m for PdS was determined from X-ray diffraction measurement. The obtained power factor of 27 μW cm-1 K-2 at 800 K is the largest value obtained for the transition metal sulfides studied so far. The maximum value of the dimensionless figure of merit is 0.33 at 800 K. These results indicate that binary bulk PdS has promising potential for good thermoelectric performance.

Heat Capacity and Thermodynamic Functions of PdS

Abstract: The temperature-dependent heat capacity of vysotskite, PdS, has been determined for the first time by adiabatic, relaxation, and differential scanning calorimetry in a wide temperature range and standard thermodynamic functions of PdS have been calculated. The 298.15-K values thus obtained are [InlineEquation not available: see fulltext.] = 43.65 ± 0.09 J/(mol K), S° = 51.98 ± 0.10 J/(mol K), Н°(298.15 К) ? Н°(0) = 8.03 ± 0.02 kJ/mol, and Ф° = 25.03 ± 0.05 J/(mol K). Using the present results and data in the literature, we obtained ΔfH°(PdS, 298.15 K) = –74.0 ± 1.0 kJ/mol and ΔfG°(PdS, 298.15 K) = –68.7 ± 1.0 kJ/mol.

Liquid-phase hydrogenation of thiophenes on palladium sulfide catalysts

The hydrogenation of thiophene, benzothiophene, and their alkyl derivatives over sulfide-containing catalysts of different compositions was studied. Palladium sulfide catalysts were active for the hydrogenation of thiophenes of different structure in hydrocarbons at 220°-300°C and 3-9.5 MPa. Thiophenes and benzothiophenes were close in reactivity. An increase in palladium sulfide concentration in the catalyst increased the reaction rate per gram of the catalyst, but only slightly influenced the specific reaction rate of hydrogenation calculated per gram of palladium. The specific activity of palladium sulfide supported on aluminosilicate was an order of magnitude higher than that of palladium sulfide without a support and the catalysts supported on the aluminum oxide and carbon. The aluminosilicate-supported catalyst was also more selective.

Synthesis and characterization of Pd(0), PdS, and Pd@PdO core-shell nanoparticles by solventless thermolysis of a Pd-thiolate cluster

Colloids of palladium nanoparticles have been prepared by the solvated metal atom dispersion (SMAD) method. The as-prepared Pd colloid consists of particles with an average diameter of 2.8±0.1 nm. Digestive ripening of the as-prepared Pd colloid, a process involving refluxing the as-prepared colloid at or near the boiling point of the solvent in the presence of a passivating agent, dodecanethiol resulted in a previously reported Pdthiolate cluster, [Pd(SC12H25)2]6 but did not render the expected narrowing down of the particle size distribution. Solventless thermolysis of the Pdthiolate complex resulted in various Pd systems such as Pd(0), PdS, and Pd@PdO coreshell nanoparticles thus demonstrating its versatility. These Pd nanostructures have been characterized using high-resolution electron microscopy and powder X-ray diffraction methods.

NaPdPS4 and RbPdPS4: Systems with infinite straight 1/∞ [PdPS4]- chains soluble in polar solvents and the structure of cubic RbPdPS4{Rb0.33P0.4S 2.23Ox}

The synthesis, crystal structures, chemical and spectroscopic properties of NaPdPS4, RbPdPS4, and RbPdPS4{Rb 0.33P0.4S2.23Ox} are described. NaPdPS4, RbPdPS4, are isostructural and crystallize in the tetragonal system I4/mcm with cell parameters a=7.3074(8)A, c=12.2308(14)A and a=8.2954(3)A, c=12.2284(4)A respectively. RbPdPS4{Rb0.33P0.4S2.23O x} is cubic, space group Pm-3n and a=12.0042(2)A. All compounds contain the same 1∞[PdPS4]- chains made of alternating square planar Pd2+ cations and tetrahedral [PS 4]3- anions. RbPdPS4{Rb0.33P 0.4S2.23Ox} contains co-crystallized highly disordered molecular species encapsulated within [Rb8] cubic cavities. Spectroscopic solid state 31P NMR, infrared and Raman data as well as elemental analysis suggest that these species could be S n2- (n=3 or 4) anions and possibly cationic [P 4S6O]6+ fragments. NaPdPS4 and RbPdPS4 exhibit exfoliative dissolution in polar solvents giving rise to solutions that show signs of complex fluid behavior.

Sulfurization-induced partially amorphous palladium sulfide nanosheets for highly efficient electrochemical hydrogen evolution

A partially amorphous palladium sulfide was synthesized by sulfurizing crystalline palladium nanosheets facilely, which shows excellent activity and stability towards hydrogen evolution in alkaline media, even superior to the performance of the commercial Pt/C catalyst. The enhanced performance could be attributed to the amorphization transformation and the nanosheet morphology.
