| 摘 要： | 利用天然沸石作载体制备TiO2/沸石复合物光催化材料,从晶相分析和热分析证实以TiCl4为钛源,锐钛矿在水相体系中可直接在沸石表面生成,并牢固结合,同时引起沸石矿物结构的调整.实验研究了在阳光照射下光催化材料对甲基橙和亚甲基蓝的分解脱色效果,不需高温处理的样品光催化性能优于经高温处理的,脱色率接近100％,结合牢固,并可重复使用.

| Abstract: | TiO2/zeolite composite photocatalysts were prepared in the water with natural zaolite and TiCl4, and the structure characterization was carried out by X-ray, IR and TG-DTA. Their photcatalytic reactivity was studied by the methyl orange and methylene blue solution decomposition effect under the sun. The results confirm that the anatase forms on the zeolite surface, and the mineral structure changes and the photocatalytic effect of low temperature treatment is more excellent than that of higher temperature treatment, the decolouration rate is in the vicinity of 100%, and can be repeatedly used. |
