This paper introduces a low-cost, highly efficient, and strong durable bifunctional electrocatalyst with hollow structured bimetallic cobalt-nickel phosphide (CoN-iP(x)) nanocages, which exhibit high electrocatalytic activity and stability for hydrogen evolution reaction and oxygen evolution reaction. When used as both anode and cathode electrocatalysts for overall water splitting, a low voltage of 1.61 V and superior stability are achieved at a current density of 20 mA cm(-2).
A low-cost, highly efficient and strong durable bifunctional electrocatalyst is crucial for electrochemical overall water splitting. In this paper, a self-templated strategy combined within-situphosphorization is applied to construct hollow structured bimetallic cobalt-nickel phosphide (CoN-iP(x)) nanocages. Owing to their unique hollow structure and bimetallic synergistic effects, the as-synthesized CoNiPx hollow nanocages exhibit a high electrocatalytic activity and stability towards hydrogen evolution reaction in all-pH electrolyte and a remarkable electrochemical performance for oxygen evolution reaction in 1.0 mol L-1 KOH. Meanwhile, with the bifunctional electrocatalyst in both anode and cath ode for overall water splitting, a low voltage of 1.61 V and superior stability are achieved at a current density of 20 mA cm(-2).
