摘要：

Thedevelopment of electrocatalysts that have long-term stabilityunder large current density is very crucial for hydrogen productionvia alkaline water electrolysis. In this paper, a novel ternary nonpreciousmetal catalyst NiMoP on nickel foam (NF) was prepared via an in situ one-step method. The overpotential of NiMoP/NF forhydrogen evolution reaction (HER) in 1 M KOH reaches only 34 and 135mV at a current density of 10 and 100 mA cm(-2), respectively.And the overpotential for HER only rose by 6 mV after 100 h of chronopotentiometry(CP) for HER in 1 M KOH. Its efficient and stable HER performancedepends on the synergistic effect of Ni, Mo, and P elements in theelectrode and a large electrochemical surface area which the uniquecrack structure obtained by adjusting the content of Mo provides.The cheap NiMoP/NF material has great potential for application incommercial alkaline water electrolysis hydrogen production.
