  • Transition metal phosphides as cocatalysts have been widely used in electrocatalysis, photoelectrocatalysis, and electrochemical energy storage. But its stability in water medium is seldom studied. Nickel phosphide (NixP) was synthesized and the reaction of NixP with H2O was studied in detail. The results showed that serious corrosion of NixP occurred when NixP was dispersed in the water while H2 was generated. At the same time, the corrosion products of PO43- and Ni2+ ions were detected. Such NixP corrosion in water is highly dependent on NixP crystal structure and components. The deposition of NiO, ZnO, and TiO2 metal oxide protective layer on NixP can improve the anticorrosion ability of NixP in the aqueous medium.
