摘　　要：采用共沉淀法制备了Cu-Al2O3纳米粉体,并将Cu-Al2O3纳米粉体负载在硅藻土上,采用X射线衍射仪和扫描电子显微镜等仪器对催化剂进行了表征。结果表明,Cu-Al2O3纳米粉体已经成功地负载在硅藻土上。对罗丹明B的降解实验表明,Cu-Al2O3@硅藻土的光催化性能明显优于改性硅藻土和Cu-Al2O3,对罗丹明B的光催化降解效率可达95%。Cu-Al2O3 nanopowders were prepared by co-precipitation method,and Cu-Al2O3 nanopowders were supported on diatomite.The catalyst was characterized by X-ray diffractometer and scanning electron microscope.The results showed that Cu-Al2O3 nanopowder had been successfully supported on diatomite.The degradation experiment of rhodamine B showed that the photocatalytic performance of Cu-Al2O3@Diatomite was significantly better than that of modified diatomite and Cu-Al2O3,and the photocatalytic degradation efficiency of Rhodamine B could reach 95%.
