Janus-Tinbco2 For Hydrogen Evolution Reaction With High Conductivity And Catalytic Activity, Li-Li Xu, Dong-Yan Ren, Xiao-Feng Zhao, Yong Yi

Journal of Electrochemistry

Exploring the potential hydrogen evolution reaction (HER) catalysts with the high activity and high conductivity has always been a hot spot in the research of renewable energy development. Ti₂C, as one of the 2D-MXene, has excellent properties relating to many active sites, mechanical stability, conductivity, etc., and has become a potential HER catalyst. However, the modification of the surface of Ti₂C by terminal O will reduce the conductivity, thereby limiting the transport of electrons between the valence band and the conduction band. In this study, an electric double layer Janus-TiNbCO₂ was constructed by Nb doping. …
