Abstract

Abstract : A strategy involving modulating the intermediate layer of an electrode was developed to promote the electrocatalysis kinetics of the electrode and therefore enhance its performance. Abstract : A hierarchical electrode consisting of a Ni foam substrate, an intermediate layer of a Mo-doped basic cobalt carbonate microwire array, and a surface layer of NiCoP was fabricated for hydrogen evolution. The introduction of the intermediate layer accounted for the low overpotential (45 mV, 10 mA cm −2 ) and high solar-to-hydrogen conversion efficiency (14.9%) in a PEC water splitting application.
