摘要/Abstract

摘要： 以金属有机骨架MOF-5为前驱体，在氮气气氛下高温处理得ZnO/C，通过水热法将ZnO/C负载到TiO2中获得ZnO/C/TiO2纳米复合光催化剂，对其晶体结构、形貌特征、成分等进行了表征，采用正交实验法考察了MOF-5处理温度、ZnO/C负载量、钛酸丁酯加入量对复合光催化剂催化降解甲基橙性能的影响. 结果表明，TiO2的比表面积为87.5 m2/g, ZnO/C/TiO2的比表面积为109.0 m2/g. 制备ZnO/C/TiO2的最佳条件为MOF-5处理温度600℃，ZnO/C负载量0.07 g，钛酸丁酯加入量1.5 mL. 甲基橙用紫外灯照射90 min，以TiO2为催化剂时降解率为62.1%，以ZnO/C/TiO2为催化剂时降解率达99.5%，光催化活性大大提高.
