摘　　要：以醋酸锌、醋酸铜和纯化的碳纳米管(CNTs)为原料利用溶胶-凝胶法,制备氧化锌(ZnO)、氧化铜(CuO)和ZnO/CuO/CNTs光催化剂。通过紫外-可见漫反射(DRS)、扫描电子显微镜(SEM)、光致发光(PL)等对复合材料的结构、能带间隙以及光学性质进行表征。研究了ZnO/CuO/CNTs光催化剂在紫外光和太阳光的照射下降解甲基橙等染料的光催化降解情况。结果表明ZnO/CuO/CNTs的光催化活性明显高于ZnO/CuO,在可见光照射下光照3h后,降解率达到80%以上。Zinc acetate, copper acetate and purified CNTs were used as raw materials, preparation of zinc oxide （ZnO）,copper oxide （CuO） and ZnO/CuO/CNTs pholocatalyst was carried by a sol-gel method. By UV-Vis diffuse reflectance spectroscopy （DRS）, scanning electron microscope （SEM）, photoluminescence （PL）, the structural, energy band gap and optical properties of composite were characterized. The photocatalytic degradation of methyl orange dyes and other used ZnO/CuO/CNTs photocatalyst under ultraviolet rays and sunlight was studied. The results showed that the catalytic activity of ZnO/CuO/CNTs significantly higher than ZnO/CuO. After 3 h irradiation by visible light, the degradation rate of ZnO/CuO/CNTs was over 80%.
