Nickel-cobalt layered double hydroxide nanosheets arrays on Ni Foam as bifunctional electrocatalysts for overall water splitting

Abstract

Bifunctional electrocatalysts which are active both for the oxygen evolution reaction (OER) and hydrogen evolution reaction (HER) could increase the efficiency of overall water splitting which is considered as the attractive technology for hydrogen production. In this work, we report the NiCo-LDH ultrathin nanosheets grown on the nickel foam as the bifunctional electrocatalyst for overall water splitting. When used as OER and HER electrodes, the NiCo-LDH/NF demonstrates excellent water-splitting performance achieving the current density of 10 mA cm−2 at 1.66 V. The synthesis of hierarchical 3D porous structure composed of 2D ultrathin nanosheets for NiCo-LDH/NF confirms the significance of structural features for high-performance overall water splitting.
