中文摘要：

在模板剂十六烷基三甲基溴化铵作用下，通过溶胶-凝胶与程序升温溶剂热法制备了纳米复合材料ZnO—TiO2（CTAB）．经X-射线衍射（XRD）、紫外-可见漫反射吸收光谱（uV—Vis／DRS）、X射线光电子能谱（XPS）、扫描电子显微镜（SEM）、透射电子显微镜（TEM）和N2吸附-脱附测试等手段对其组成、结构和形貌等进行了表征．结果显示，合成产物ZnO—TiO2（CTAB）主要晶型为ZnO纤锌矿，并部分生成ZnTiO2．同时，该合成产物经CTAB作用后，其对光的吸收发生明显红移，且平均孔径明显变小，BET值增大．在紫外光、可见光、模拟日光和微波辅助等不同模式光催化降解罗丹明B的实验研究中，与未经CTAB作用的样品ZnO—TiO2相比，ZnO—TiO2（CTAB）具有更高的光催化性能．同时，该复合材料在紫外光条件下，对甲基橙、罗丹明B、结晶紫、亚甲基蓝和龙胆紫5种不同结构染料的光催化中均表现出良好的降解效果．

英文摘要：

The nano-composite ZnO-TiO2 under cetyhrimethyl ammonium bromide（CTAB） was prepared by the sol- gel method combined with temperature-programmed hydrothermal treatment. The phase composition, structure and morphology of the nano-composite ZnO-TiO2 （CTAB） were well-characterized by X-ray diffraction（ XRD）, diffuse reflectance （ UV-Vis/DRS ）, X-ray photoelectron spectroscopy （ XPS ）, Scanning electron microscopy （ SEM ）, Transmission electron microscopy （TEM） and N2 adsorption-desorption measurement. Results showed that the syn- thesized product ZnO-TiO2（CTAB） had mainly the ZnO wurtzite and part ZnTiO3 generated. Meanwhile, the ab- sorption band of as-product ZnO-TiO2 （CTAB） was obviously red shifted with CTAB effect, and the average pore size of ZnO-TiO2 （CTAB） was obviously reduced, moreover, its BET was increased. Compared with ZnO-TiO2 without CTAB, the nano-composite ZnO-TiO2 （CTAB） had better photocatalytic properties in the different modes in- cluding ultraviolet, visible light, simulated sunlight and microwave-assisted photocatalytic degradation of Rhoda- mine B. In addition, the nano-composite ZnO-TiO2 （CTAB） showed good degradation for five different structure dyes including methyl orange, Rhodamine B, Crystal violet, Gentian violet and Methylene blue under UV light irra- diation.
