摘要: 采用水热法制备铜/石墨烯(Cu/RGO)复合材料,通过XRD、FTIR、SEM和TEM对材料的结构和形貌进行表征,并考察了复合材料在H2O2辅助作用下对次甲基蓝(MB)的催化作用。结果表明,该复合材料中石墨烯所负载的铜颗粒尺寸较小且分布均一,对MB的催化效果良好,0.18 g·L-1复合催化剂在300 min内对MB的脱色效果可达90.7%,经过5次循环仍有88.0%以上。

Abstract: Copper/graphene composite materials were fabricated by hydrothermal method,and its structure and morphology were characterized by XRD,FTIR,SEM and TEM,the catalytic performance of this composite toward methylene blue was investigated at hydrogen peroxide solution.The results shown that the copper particles size were small and uniform distribution loading graphene sheets in the composite material,which exhibits good catalytic activity for the decolorization of methylene blue,the 0.18 g·L-1 composite catalyst with in 300 min on the decolorization rate of methylene blue can reach 90.7%,after 5 cycles on the catalytic efficiency of methylene blue test is still more than 88.0%.
Keywords: copper/graphene  composites  catalytic  methylene blue
