Applications, performance enhancement strategies and prospects of NixPy in electrocatalysis

Abstract

Developing low-cost and high-efficiency electrocatalysts is the key to making energy-related electrocatalytic technologies commercially feasible. In recent years, nickel phosphide (Ni_xP_y) electrocatalysts have received extensive attention due to their multiple active sites, adjustable structure and composition, and unique physicochemical properties. In this review, the latest progress of Ni_xP_y in the field of electrocatalysis is reviewed from the aspects of the properties of Ni_xP_y, different synthesis methods, and ingenious modulation strategies. The significant enhancement effects of elemental doping, vacancy defect, interfacial engineering, synergistic effect, and the external magnetic field excitation-enhanced strategy on the electrocatalytic performance of Ni_xP_y are emphasized, Moreover, a forward-looking outlook for its future development direction is provided. Finally, some basic problems and research directions of Ni_xP_y in high-efficiency energy electrocatalysis are presented.
