Preparation and photocatalytic activity of Cu/reduced graphene oxidephotocatalytic composites

  • 摘要: 以乙酸铜和氧化石墨烯(GO)为原料,抗坏血酸为还原剂,采用液相化学法合成Cu/还原氧化石墨烯(Cu/RGO)复合材料。通过XRD、SEM、TEM、FTIR和Raman对材料结构及形貌进行表征,并考察Cu/RGO复合材料在H2O2辅助作用下对亚甲基蓝(MB)的光催化作用。结果表明:Cu颗粒均匀分布在RGO片层上,相比于纯Cu,Cu/RGO复合材料的光催化性能明显提高,Cu/RGO复合材料用量为0.06 g/L时,对MB显示出最佳的催化效果,200 min内脱色率达到了92.5%,经过5次循环后脱色率仍有88.0%以上。
    Abstract: Cu/reduced graphene oxide (RGO) photocatalytic composites were prepared through the liquid phase chemical method by using cupric acetate and graphene oxide (GO) as the precursors and ascorbic acid as the reducing agent. The Cu/RGO composites were characterized by XRD, SEM, TEM, FTIR and Raman, the photocatalytic performance of composites toward methylene blue was investigated under the aid of H2O2. The results show that the Cu particles uniformly distribute on the RGO sheets, and the Cu/RGO composite exhibites good catalytic activity for the decolorization of methylene blue. The Cu/RGO composite shows the best catalytic performance for MB when the composite dosage is 0.06 g/L, the decolorization rate reach 92.5% in 200 min, and the decolorization rate remains 88.0% after 5 cycles.
