▎ 摘　　要

A novel method for the rapid hydrogenation of graphene oxide (GO) is established using nickel nanoparticles (Ni NPs) and through electrochemical reaction. In-situ generated hydrogen and enhanced spillover on graphene sheet makes the hydrogenated graphene oxide (HGO) easily at room temperature. Initially, a well intercalated Ni-GO species was produced due to the nanosize effect of nickel nanoparticles and promoted the homogenous hydrogenation of GO sheets. The structure, composition and morphology of GO, Ni-GO and HGO were fully characterized. I-V characteristics of HGO showed very interesting properties such as hysteresis, resistive switching and rectifier properties.
