摘要
以碳微球为模板,采用溶胶凝胶法、水热法等方法分别制备了TiO2微球、ZnO微球和TiO2/ZnO复合微球,采用扫描电子显微镜、X-射线衍射仪等对样品进行了表征,结果表明:制备的TiO2微球、ZnO微球和TiO2/ZnO复合微球,各微球直径在5~10μm之间。在紫外光和可见光下研究了制备的光催化剂对亚甲基蓝溶液和湖水的光催化性能,光催化实验表明:三种微球中TiO2/ZnO复合微球具有良好的光催化性能。
The TiO2 microspheres,ZnO microspheres and TiO2/ZnO composite microspheres were obtained by Sol-gel method and hydrothermal method with Carbon microspheres as a template. The samples were characterized by SEM and X-ray diffractometer. The result indicates that TiO2 microspheres,ZnO microspheres and TiO2/ZnO composite microspheres were obtained and the diameter of them were 5-10 μm. The photocatalytic properties of the obtained photocatalyst on methylene blue solution and lake water were studied under UV light and the sunlight. Photocatalytic experiments have shown that among the three microspheres,the TiO2/ZnO composite microspheres have better photocatalytic activity.
