Kinetic analysis of hydrogen evolution at Ni–Mo alloy electrodes

Electrodeposited Pd-Ni-Mo film as a cathode material for hydrogen evolution reaction

“…Because of that, it is of great interest to researchers to develop electrode materials with higher electrocatalytic activity for HER. The performance of nickel and nickel alloy electrodes including Ni, Ni-Mo [3][4][5] and Ni-Co alloys [6] for HER in alkaline solutions has been widely investigated. Besides, noble metals such as Pt, Pd, Ru, etc.…”

Surface morphology and electrochemical characterization of electrodeposited Ni–Mo nanocomposites as cathodes for hydrogen evolution

“…Among these composites are those containing metals like Al, Ti, V, Mo, which could not be directly deposited from aqueous solutions. Incorporating such powdered components to the metal matrix leads to obtain a new kind of composite material which could be applied as electrode materials [5][6][7][8][9]. Ni based binary composite coatings like Ni-Mo, Ni-Zn, Ni-Co, Ni-W, Ni-Fe and Ni-Cr were tried for hydrogen electrodes; out of these electrodes, Ni-Mo was found to be best and most stable electrode with an overpotential of 0.18 V in 6 M KOH solutions [10].…”

The investigation of the kinetics and mechanism of hydrogen evolution reaction on tin

“…Electrochemical impedance spectroscopy (EIS) has been often used in the studies of HER kinetics on various crystalline and amorphous forms of metals and metal alloys, where Nyquist diagrams with one or two relaxation times have been observed [18][19][20][21].…”
