摘要：
以2-甲基咪唑、醋酸锌与硝酸铈为原料，在常温下制备了系列掺入Ce的ZIF-8金属有机框架材料，然后通过高温焙烧制得表面有缺陷的Ce-ZnO微纳米材料。利用XRD、TG、SEM等对制备的Ce-ZnO进行了表征，并以高压汞灯为光源，以有机染料罗丹明B为目标污染物，考察了Ce-ZnO的光催化活性。结果表明，相比于ZIF-8高温热解制得的ZnO，Ce-ZnO具有更好的光催化活性和稳定性，当Ce掺杂量为1.0%时，其性能最佳。

Abstract:
A series of Ce-doped ZIF-8 metal-organic framework materials were prepared from 2-methylimidazole, zinc acetate, and cerium(Ⅲ) nitrate at normal temperature, and then were roasted under high-temperature to obtain the surface defected Ce-ZnO micro-nanometer materials. The Ce-ZnO catalysts were characterized by XRD, TG, SEM and EDS. High pressure mercury lamp as light source, the photocatalytic activities of Ce-ZnO catalysts were investigated by the degradation of the soluble organic dye rhodamine B. Compared with ZnO catalyst prepared by high-temperature pyrolysis of ZIF-8, Ce-ZnO catalyst had better photocatalytic activity and stability. Moreover, the best performance of Ce-ZnO catalyst was found at the Ce doping amount of 1.0%.
