New criteria for the applicability of combustion synthesis: The investigation of thermodynamic and kinetic processes for binary Chemical Reactions

Combustion synthesis is a novel technique that utilizes the exothermic heat of a chemical reaction to maintain the reaction and to rapidly prepare materials. But, hitherto, none of unified criterion for the validation of combustion synthesis has been proposed. Herein, we proposed the conditions need to be met. In terms of kinetics, at the adiabatic temperature (Tad), the diffusion distance of atoms (lTad) within 0.1 s should be larger than the particle size of the reactants(d), that is, lTad≥d. For systems that satisfy Tad/Tm,L≥1(where Tm,L is the melting point of the low-melting point component of the reactants), the presence of a liquid phase significantly increases the atomic diffusion distance from nanometers to tens of microns, making the criterion lTad≥d simplified to Tad/Tm,L≥1 in most situations. In terms of thermodynamics, the system needs to ensure that the reaction components are in an activated state, that is, Tad/Tm,H ≥0.7, where Tm,H is the melting point of the high-melting point component. The criteria for the SHS reactions proposed in this study further improve the theoretical understanding of SHS reactions, and provide guidance for exploring the ultra-fast synthesis of binary and multicomponent compounds.

Nanoporous NiSb to Enhance Nitrogen Electroreduction via Tailoring Competitive Adsorption Sites

Ambient nitrogen reduction reaction (NRR) is attracting extensive interest but still suffers from sluggish kinetics owing to competitive rapid hydrogen evolution and difficult nitrogen activation. Herein, nanoporous NiSb alloy is reported as an efficient electrocatalyst for N2 fixation, achieving a high ammonia yield rate of 56.9 μg h?1 mg?1 with a Faradaic efficiency of 48.0%. Density functional theory calculations reveal that in NiSb alloy, Ni favors N2 hydrogenation while the neighboring Sb separates active sites for proton and N2 adsorption, which optimizes the adsorption/desorption of intermediates and enables an energetically favorable NRR pathway. This work indicates promising electrocatalytic application of the alloys of 3d and p block metals toward the NRR and provides an intriguing strategy to enhance the reduction of inert molecules by restraining the competitive hydrogen adsorption.

Refinement of the Microwave-Assisted Polyol Process for the Low-Temperature Synthesis of Intermetallic Nanoparticles

The microwave-assisted polyol process was applied to synthesize phase-pure micro- or nanocrystalline intermetallic phases in the systems T–M (T = Co, Ni, Rh, Pd, Ir, Pt and M = Sn, Sb, Pb, Bi). Reaction temperatures range between 240 and 300 °C, and reaction times of a few minutes up to 1 h are sufficient. For optimization of the syntheses, the reaction temperature, reaction time, and metal precursors were changed. To obtain phase-pure samples the process was further modified by the addition of potassium hydroxide, oleylamine, or oleic acid. Single-phase powders of a variety of intermetallic compounds were synthesized. Although not stable at the temperature of synthesis, high-temperature phases are accessible as well. The microwave-assisted polyol process opens up the possibility to synthesize intermetallic compounds through a fast and easily applicable one-step route, without utilization of strong and often toxic reducing agents.

Antimonato polyoxovanadates with structure directing transition metal complexes: Pseudopolymorphic{Ni(dien)2}3[V 15Sb6O42(H2O)]·nH 2O compounds and {Ni(dien)2}4[V 16Sb4O42(H2O)]

Three new poloxovanadates were synthesized under solvothermal conditions and were structurally characterized. The two compounds with composition {Ni(dien)2}3[V15Sb6O 42(H2O)]·nH2O (n = 12 and 8; dien = bis(2-aminoethyl)amine or diethylenetriamine) are pseudopolymorphs crystallizing in different space groups. The compounds were obtained by applying identical reaction slurries but using different reaction temperatures. Both compounds feature the [V15Sb6O42(H2O)] 6- anion which is the antimony analogue to the single molecule magnet [V15As6O42(H2O)]6-.

In 1 several unusual short inter-cluster Sb...O contacts lead to the formation of three different super-clusters with composition V60Sb24O168. The 12 unique {Ni(dien)2}2+ complexes adopt all three possible configurations. In 2 the special arrangement of the {Ni(dien)2} 2+ complexes around the cluster anion prevents inter-cluster Sb...O contacts. The main structural motif of the third compound {Ni(dien)2}4[V16Sb4O 42(H2O)] (3) is the [V16Sb4O 42(H2O)]8- cluster anion consisting of two perpendicular eight-membered rings of VO5 pyramids.

Solution synthesis of nanoparticular binary transition metal antimonides

The preparation of nanoengineered materials with controlled nanostructures, for example, with an anisotropic phase segregated structure or a regular periodicity rather than with a broad range of interparticle distances, has remained a synthetic challenge for intermetallics. Artificially structured materials, including multilayers, amorphous alloys, quasicrystals, metastable crystalline alloys, or granular metals, are mostly prepared using physical gas phase procedures. We report a novel, powerful solution-mediated approach for the formation of nanoparticular binary antimonides based on presynthesized antimony nanoparticles. The transition metal antimonides M-Sb (M = Co, Ni, Cu 2, Zn) were obtained with sizes ranging from 20 and 60 nm. Through careful control of the reaction conditions, single-phase nanoparticular antimonides were synthesized. The nanophases were investigated by powder X-ray diffraction and (high resolution) electron microscopy. The approach is based on activated metal nanoparticles as precursors for the synthesis of the intermetallic compounds. X-ray powder diffraction studies of reaction intermediates allowed monitoring of the reaction kinetics. The small particle size of the reactants ensures short diffusion paths, low activation barriers, and low reaction temperatures, thereby eliminating solid-solid diffusion as the rate-limiting step in conventional bulk-scale solid-state synthesis.

Reductive synthesis of metal antimonides

A new low temperature synthetic route to binary and ternary metal antimonides is reported. Binary transition metal antimonides prepared include CoSb3, CoSb2, CoSb, NiSb, NiSb2, Cu 2Sb and Mo3Sb7; new ternary compositions prepared include the series Co1-xNixSb (0.1 ≤ x ≤ 0.9). The intermetallic SnSb has also been prepared by this route. The synthetic method is simple and does not require the use of very high temperatures, multi-step reactions or reaction under vacuum. Compounds were synthesised by the reduction of mixed metal oxides under 10% hydrogen in argon at moderate temperatures (approx. 450 °C). The route affords some control over the stoichiometry of the product. High purity binary phases formed include CoSb 3, CoSb, NiSb, Cu2Sb and SnSb. Owing to the significantly different reduction temperatures of the starting metal oxides, Mo 3Sb7 was formed with impurities of MoO2 and Sb metal. CoSb2 and NiSb2 were formed with impurities of CoSb3 and NiSb, respectively.
