▎ 摘　　要

Nitrogen doped graphene (N/GN) and nitrogen doped graphene/copper-based catalyst (Cu-N/GN) were fabricated by hydrothermal treatment and ultrasonic-assisted equal volume impregnation method, respectively. The microstructure, morphology and elemental composition of Cu-N/GN catalyst were respectively characterized by XRD, SEM, TEM, N-2 adsorption-desorption, XPS and XAES. The catalytic performance of Cu-N/GN toward acetylene hydrochlorination was investigated. The results shown that the size of Cu particles is small and Cu species uniform distribution loading N/GN sheets with relatively low amount of Cu (3.6%) in the catalyst. The Cu-N/GN catalyst exhibits good catalytic activity for the acetylene hydrochlorination, and its acetylene conversion and vinyl chloride selectivity are about 68% and 99%, respectively.
