采用喷雾干燥和煅烧的方法制备了碳纳米管/石墨烯-氧化铜(CNTs/rGO-CuO)复合粉体,对复合粉体进行了形貌观察和物相分析,讨论了分解温度、碳纳米管(CNTs)和氧化石墨烯(GO)的质量比、CNTs和GO的质量分数对复合粉体形貌和光催化性能的影响,并对制备工艺进行了优化.结果表明:当分解温度为210℃、CNTs与GO的质量比为1∶1、CNTs和GO的质量分数为10％时,制备的复合粉体性能最佳;CNTs与GO形成了一种球状结构,CuO颗粒均匀地分布在球体表面;在可见光照射20 min后,该复合粉体对溶液中甲基橙(MO)的最大降解率能达到98.3％.%Carbon nanotubes and reduced graphene oxides with CuO (CNTs/rGO-CuO) composite powder was synthesized by spray drying and post-calcinating method,and the phase and morphology were analyzed.The synthesis conditions that had a significant effect on the morphology and photocatalytic performance of composite powder such as decomposed temperature,carbon nanotubes (CNTs) to graphene oxides (GO) mass ratio,CNTs and GO mass fraction were discussed.The preparation process was optimized.The results show that when the decomposed temperature was 210 ℃,CNTs to GO mass ratio was 1:1,CNTs and GO mass fraction was 10％,the composite powder had the best property.CNTs and rGO formed a spherical structure and CuO particles were uniformly distributed on the surface of the spherical structure.98.3％ degradation of methyl orange (MO) could be obtained after 20 min under visible light.
