Low-cost industrially available molybdenum boride and carbide as platinum-like catalysts for the hydrogen evolution reaction in biphasic liquid systems
Optional Fields
Hydrogen evolution reaction Electrocatalysis Molybdenum carbide Molybdenum disulphide Liquid liquid interface
Rarely reported low-cost molybdenum boride and carbide microparticles, both of which are available in abundant quantities due to their widespread use in industry, adsorb at aqueous acid-1,2-dichloroethane interfaces and efficiently catalyse the hydrogen evolution reaction in the presence of the organic electron donor decamethylferrocene. Kinetic studies monitoring biphasic reactions by UV/vis spectroscopy, and further evidence provided by gas chromatography, highlight (a) their superior rates of catalysis relative to other industrially significant transition metal carbides and silicides, as well as a main group refractory compound, and (b) their highly comparable rates of catalysis to Pt microparticles of similar dimensions. Insight into the catalytic processes occurring for each adsorbed microparticle was obtained by voltammetry at the liquid-liquid interface. doi=10.1039/c2cp44522k
