Ultra-thin N-doped-graphene encapsulated Ni nanoparticles coupled with MoO₂ nanosheets for highly efficient water splitting at large current density

Abstract

Ultra-thin N-doped-graphene encapsulated Ni nanoparticles coupled with MoO₂ nanosheets are prepared for HER and OER. As used for overall water splitting, it can work for 196 h at 1000 mA cm⁻².
