Abstract: Water electrolysis will become the core technology of environmental production for hydrogen industry in the future. It is very important to study new cathode materials for reducing the cathode overpotential. Because it not only can reduce energy consumption and the cost of water electrolysis, but also can enhance the stability and safety of production. This paper mainly discusses the research status of hydrogen electrode materials for alkaline water electrolysis. Based on the major improvement of catalytic activity for hydrogen evolution reaction, this paper mainly focuses on the electrodepositing preparation method for three kinds of nickel-based electrodes, which are alloy hydrogen evolution electrode, composite hydrogen evolution electrode, and porous hydrogen evolution electrode. The existing problems on hydrogen evolution electrode in experimental research and industrial application are analyzed. In the end, it is pointed out that the more catalytic activity and more stable electrochemical performance of multivariate composite electrodes based on electrodepositing preparation will be the future of hydrogen electrode development.

Key words: electrolysis, hydrogen production, catalysis, hydrogen evolution electrode, electrolytic deposition
