Cathodic hydrogen evolution on molybdenum in NaOH solutions

Syngas production from electrochemical reduction of CO2: current status and prospective implementation

“…During the last few decade, several elements, such as Cu, Au, Pd, Rh, Fe and Mo, [63][64][65] Ni, [66][67][68] Ru, 69,70 and Co, 71 have been investigated with the aim of finding a suitable replacement for Pt that would be the most active H2 evolution catalysts. Because of the promising results that have recently been achieved, HER catalysts based on earth abundant elements, such as Co, Fe, and Ni, have been at the centre of the attention in current research.…”

Electrochemical performance of tungsten electrode as cathode for hydrogen evolution in alkaline solutions

“…According to these recorded values, W is the promising cathode for hydrogen evolution. It shows remarkably high rate of hydrogen evolution comparable to that of Pt at lower overpotential [12].…”

“…The recorded steady state potentials of the three metals Pt, Cu and W were À50, À280 and À630 mV, respectively. The remarkably negative steady state potential of W suggests that the HER on W will occur at lower overpotential compared to Pt, especially [12].…”

“…The investigated cathodes have remarkably high catalytic activity for the HER. Mo was proved to be a promising cathode for hydrogen production, it is even better than Pt in both alkaline and acidic solutions [12,14]. The rate of the HER on Mo remains constant after prolonged electrode application.…”

Cyclic voltammetry growth and characterization of Sn–Ag alloys of different nanomorphologies and compositions for efficient hydrogen evolution in alkaline solutions

“…Ag. 35 The hydrogen reduction overpotential and current density are considered the main characters to control the electrodes activities and rates of HERs. Hence, the rate of hydrogen evolution is directly proportional to the cathodic current density.…”
