摘要

以有机金属骨架材料MOF-5为前驱体,一步法将ZnO与TiO₂复合制备ZnO/TiO₂材料。通过扫描电镜、红外光谱、X射线衍射(XRD)、UV-Vis光等方法对ZnO/TiO₂复合光催化剂的结构和性能进行表征,并以亚甲基蓝为目标降解物,评价ZnO/TiO₂复合材料的吸附降解性能及循环效率。结果表明:所制备的ZnO/TiO₂光催化剂表面较粗糙,XRD表征有ZnO和TiO₂特征峰,ZnO的加入可提高TiO₂对波长小于600nm光的吸收;ZnO/TiO₂复合材料在模拟可见光和紫外光下及循环吸附降解性能都优于TiO₂,模拟可见光下5次重复循环利用ZnO/TiO₂的吸附降解率均能达97%以上。

Abstract

ZnO/TiO₂ composite was synthesized by one-step method using metal-organic framework (MOF-5) as precursor.The structure and performance of ZnO/TiO₂ composite photocatalyst was characterized by SEM,FT-IR,XRD,UV-Vis and methylene blue was used as the target degradation material to evaluate the adsorption-degradation performance and cycling efficiency.The results showed that the surface of the prepared ZnO/TiO₂ was rougher,the ZnO and TiO₂ characteristic peaks were respectively showed in the XRD diagram,and the addition of ZnO could increase the ZnO/TiO₂'s absorption of the light at wavelength smaller than 600nm.The adsorption-degradation performance of ZnO/TiO₂ under simulated white light and ultraviolet light were better than that of TiO₂.The adsorption-degradation rates of ZnO/TiO₂ under simulated white light could reach more than 97% after five repeated cycles.
