摘要(Abstract)：

为提升TiO_2/ZSM-5的可见光光催化和抗菌性能，以Cu(NO_3)_2、Ti(SO_4)_2和ZSM-5为原料，采用浸渍-煅烧法制备了具有可见光光催化/抗菌功能的CuO/TiO_2/ZSM-5复合材料。采用X射线衍射分析仪（XRD）、X射线光电子能谱仪（XPS）、气体吸附仪、扫描电子显微镜-能谱仪（SEM-EDS）、紫外-可见光漫反射光谱仪（UV-Vis DRS）、X射线荧光光谱仪（PL）、电子顺磁共振波谱仪（EPR）和电感耦合等离子体发射光谱仪（ICP）等对材料的组成结构进行表征，采用甲基橙溶液评价材料的光催化性能，采用大肠杆菌和金黄色葡萄球菌评价材料的抗菌性能。结果表明：浸渍-煅烧法可成功制得大比表面积和孔体积的CuO/TiO_2/ZSM-5复合材料。CuO/TiO_2摩尔比为0.5%时，所得0.5CuO/TiO_2/ZSM-5材料具有相对较低的电子-空穴对复合几率、较宽的光响应范围、较高的·O_2~-和·OH等活性物种产生量，表现出优异的光催化和抗菌性能，其在氙灯光照150 min后，对甲基橙的去除率可达95%，在避光条件和光照5 min后，对大肠杆菌的抗菌率达75.2%和83.3%，对金黄色葡萄球菌的抗菌率达97.6%和98.5%。
