Research progress of nickel-based phosphide composites in improving of catalytic water electrolysis for hydrogen evolution performance
Nickel-based phosphorus compounds have been shown to have good hydrogen evolution ability in electrolytic wa-ter because of their hydrogen-like electronic structure and excellent stability.Because its intrinsic activity is insufficient,the conductivity is not high and the stability is poor,so practical application of monometallic phosphide is limited.The prepara-tion methods of nickel-based phosphide composites with novel structure,excellent performance and high stability were re-viewed.The research results of regulating the electronic structure and microstructure of electrode materials,promoting long-term electrolytic stability,increasing specific surface area and improving electrical conductivity through heteroatom doping,morphology regulation,combination of self-supporting materials and new composite materials(carbon nanotubes,graphene,graphyne,MXene)were summarized and analyzed.It provided the research direction for exploring new nickel-based phos-phide composite materials with high catalytic activity and stable structure.
