| 摘 要： | 采用Sol-Gel浸涂法制得负载于γ-Al2O3空心球表面的N/TiO2,应用于自制流化床反应器,考察了浸涂方式、有氧、无氧状态以及外加H2O2对降解效果的影响。结果显示:在卤钨灯照射下,负载型N/TiO2显示出一定的光催化活性;多层交叉浸涂、有氧状态及外加H2O2均提高了光催化活性。

| Abstract: | The application of N/TiO2 which were prepared by Sol-Gel dip-coating method loading on the surface of hollow sphere of y-Al2O3 to the fluid-bed reactor was investigated preliminarily. Such factors as dip-coating mode, existence of oxygen or without oxygen, presence of H2O2 were all investigated. The results showed that the load type N/TiO2, exhibited some activity under irradiation of tungsten halide lamp. Multi-dip-coating mode, existence of oxygen and H2O2 would improve the photoactivity. |
