| 摘 要： | 通过溶胶-凝胶技术制备了不同比例(3:1、1:1、1:3)的纳米复合光催化材料TiO2-ZrO2,采用XRD、N2吸附、SEM-EDX和TPD等测试手段对其进行了表征,探讨了比例不同的TiO2-ZrO2结构的变化规律以及这种变化对催化剂催化活性的影响.通过紫外区和可见区的光催化降解染料亚甲基蓝、罗丹明B的实验,考察了其光催化活性.实验结果表明,不同比例的纳米复合光催化材料TiO2-ZrO2的催化活性均高于单体TiO2和单体ZrO2.

| Abstract: | The composite TiO2-ZrO2 was prepared by sol-gel method and characterized by XRD,nitrogen absorption-desorption,SEM-EDX and TPD techniques. The effect of proportions of TiO2-ZrO2 on the structure and catalytic activity was investigated. The results indicated the composite was active to decompose methylene blue and rhodamine B in aqueous,and the photocatalytic activity was higher than that of TiO2 and ZrO2 individually. |
