CoP nanoparticles anchored on N,P dual-doped graphene-like carbon as a catalyst for water splitting in non-acid media

Abstract

Designing earth-abundant, active and stable water splitting bifunctional catalysts operating in the same media is curial for large-scale water electrolysis. CoP nanoparticles anchored on N,P dual-doped mesoporous graphene-like carbon (CoP@NPMG) exhibits as an outstanding bifunctional electrocatalyst for both hydrogen evolution reaction and oxygen evolution reaction in a wide pH range. The synthesis method of CoP@NPMG is template-free and simple, along with all precursors are easily obtained, all these factors contribute to the feasibility of practical large-scale fabrication. Applied as bifunctional electrodes, CoP@NPMG enables high-performance water splitting with current density of 10 mA cm-2 at cell voltage of only 1.58 V and 1.74 V in 1 M KOH and 1 M PBS, respectively. In addition, CoP@NPMG offers excellent catalytic stability in all pH values.
