摘要

Abstract

Electrochemical water splitting is one of the most efficient strategies to generate clean energy H

. Herein

a novel hollow Co

/CuS@CoNi-LDH nanocomposite was designed. This hollow Co

/CuS@CoNi-LDH achieved OER overpotential of 220 mV

HER overpotential of 136 mV

respectively

at the current density of 10 mA cm

−2

. Notably

the hollow Co

/CuS@CoNi-LDH serving as both anode and cathode is assembled into a two-electrode water splitting device

and the potential of no more than 1.74 V is required to achieve the overall water splitting efficiency of 10 mA cm

−2

. This work provides a promising bifunctional catalyst for overall electrochemical water splitting.
