摘要
以玻璃纤维布为载体,分别用浸渍法和黏结剂法制备了负载型TiO2光催化剂,用SEM观察了2种方法中TiO2在玻璃纤维表面的负载情况。实验中以甲基橙为对象,以紫外线高压汞灯为光源,用所制备的2种玻璃纤维固定化TiO2光催化剂对甲基橙进行了光降解研究;分析了黏结剂法中黏结剂对TiO2光催化性能的影响;并分析了2种负载型光催化剂涂层与基体间的结合牢固性。结果表明,2种负载型光催化剂对甲基橙都有较好地脱色效果,而且两者与基体结合牢固性均良好。
Using fiber glass cloth as the carrier, the titania photo-catalyst coated on fiber glass cloth was prepared by the dipping method and the adhesive method. The coating layer of the samples obtained by the two methods were observed by SEM. The supported photocatalysts were used to carry out photocatalytic degradation of methyl orange with an ultraviolet high pressure mercury lamp as the light source. The influence of the binder on the photoactivity of the supported catalyst was analyzed. The fastness of combination of the coating and the substrate was investigated. The results show that the two kinds of supported titania catalysts both produce good effects of decolouring methyl orange solution and they have good fastness in combination with the substrate.
