Abstract

Abstract : Self-supported porous NiS/VS heterostructured nanosheets were designed towards efficient electrocatalytic water splitting. Abstract : Herein, NiS/VS heterostructures are designed as efficient electrocatalysts for overall water splitting. Vanadium modifies the electronic structure and induces a large amount of active sites. Strong interactions between the interfaces of the heterostructure lead to lower charge transfer resistance and enhance the intrinsic activity of active sites. As a result, NiS/VS only needs a potential of 158 mV for the HER and 240 mV for the OER to achieve 10 mA cm −2 . When used in a two-electrode electrolyzer, NiS/VS can achieve 10 mA cm −2 at a low voltage of 1.64 V. Our research may provide a new approach for constructing bifunctional heterostructure electrocatalysts for highly efficient overall water splitting.
