The N, P co-doped carbon-loading Ni3P@Ni heterojunction nanocomposites derived from polybenzimidazoles grafted with oxygen-phosphorus group as high-efficiency electrocatalyst for oxygen evolution reaction

Ni 3 P@Ni/CNP exhibits excellent OER electrocatalytic activity. The current density of 10 mA cm −2 in 1 M KOH electrolyte only needs an overpotential of 239 mV in the presence of the catalyst, and it showed excellent stability.
