摘要
研究了采用溶胶-凝胶法制备Fe2O3和TiO2两种光催化剂,将其负载于不同的固体颗粒上以提高光催化剂的光量子效率及回收率。并探索了采用固载型复合光催化剂处理亚甲基兰、结晶紫等染料废水和甲醛、乙醇、TNT、十四烷等多种有机物废水的难易程度及可行性。显示了固载复合型光催化剂比单一光催化剂具有更高的处理效率与更广泛的应用前景。
In this article, photocatalyst of Fe2O3 and TiO2 prepared in sol gel were loaded to solid particles in order to improve their photos efficiency and photocatalyst reclaim. The experimental results showed that the immobilization compound photocatalyst could dispose waste,water such as crystalloid and dyestuff, and some wastewater containing formaldehyde, ethanol and trinitrotoluene. The comparison of the decomposition level of the water had also been made. It was shown that solid loaded compound photocatalyst was more effective than single photocataly and had broad application.
