| 摘 要： | 本文以氧化石墨烯和钛酸丁酯为原料,利用水热法一步制备了TiO2/石墨烯复合光催化材料,研究了氧化石墨烯用量、反应温度、反应时间对TiO2/石墨烯复合材料光催化活性的影响。采用XRD,SEM,TEM和氮气吸附-脱附实验(BET)对复合光催化材料的物相、颗粒粒径、形貌及比表面积进行了表征。结果表明,本实验最佳条件是:氧化石墨烯1mg,制备温度为180℃,反应时间为16 h。产物中的TiO2为锐钛矿晶型,其平均粒径约为18 nm。复合材料的比表面积为170m2/g,平均孔径为12.45 nm。在可见光照射(λ>420nm)下以TiO2/石墨烯为光催化剂对有机染料罗丹明B(Rhodamine B,RhB)进行光催化降解,其光催化活性明显高于相同条件下制备的TiO2。
