| 摘 要： | 利用溶胶-凝胶法原位制备了二氧化钛/石墨烯(TiO2-GE)复合光催化剂,研究了纯TiO2以及不同方法制备的TiO2-GE复合光催化剂对亚甲基蓝及罗丹明B光催化降解性能。结果表明:石墨烯的引入提高了TiO2的光催活性,这主要是得益于石墨烯优异的电子传输性能及较好吸附特性。不同方法制备TiO2-GE复合催化剂的光催化活性也存在较大差别。原位制备的TiO2-GE复合光催化剂表现出最佳的光催化活性。 |

| Abstract: | Titania/graphene (TiO2-GE) composite photocatalyst has been in-situ synthesized by sol-gel method. The photocatalytic performance of pure TiO2 and TiO2-GE composite obtained by different methods has been investigated using the photodegradation of methylthionine chloride and rhodamine B as model reactions. The results show that the photocatalytic activity of TiO2-GE composite is much higher than that of pure TiO2 due to rapid electronic transmission and the good adsorption of GE. Additionally, the as-prepared TiO2-GE composites obtained with different preparation methods have different activities in the photodegradation of methylthionine chloride and rhodamine B. The TiO2-GE composite synthesized by in-situ sol-gel method shows the highest photocatalytic activity. |
