| 摘要: 采用水热法合成掺氮石墨烯（N/GN），通过超声辅助等体积浸渍法制备掺氮石墨烯-铜基催化剂（Cu-N/GN）。通过XRD、SEM、TEM、N2吸附脱附、XPS和XAES对催化剂的微观结构、形貌及元素组成进行表征，并考察Cu-N/GN对乙炔氢氯化反应的催化性能。结果表明：在催化剂中铜颗粒尺寸较小、均匀分布于N/GN片层上，且铜含量较低（3.6%）；Cu-N/GN对乙炔氢氯化反应的催化效果良好，乙炔转化率为68%，氯乙烯选择性为99%。 |

| Abstract: 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, N2 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. |
