As one of the efficient, continuous and clean hydrogen production methods, electrochemical water splitting depends on economical, efficient and stable electrocatalysts to a great extent. In this paper, Co2+ and Ni2+ were adsorbed on cation exchange resin by stirring and soaking, and then a series of cobalt-nickel bimetallic phosphides NiCoP-x@C were synthesized by high temperature calcination. The experimental results show that NiCoP-x@C has a porous structure and is rich in porous nanoparticles, which makes a major contribution to OER. In addition, bimetallic doping and the increase of P content also promote the catalytic activity of oxygen evolution reaction. For OER, the overpotential of NiCoP-2B@C is 366 mV, and Tafel is 52.09 mV dec-1. This paper provides a new strategy for the design and preparation of OER catalysts.
