ZnO/BiOI微球的合成及其光催化性能(英文)
发布时间:2021-03-31 15:24
通过一步溶剂热法合成ZnO/BiOI纳米复合材料,在Bi(NO3)3·6H2O、KI、ZnO和乙二醇(EG)溶剂中,制备出的样品尺寸和形貌采用X射线粉末衍射(XRD)、场发射扫描电镜(FESEM)、高分辨透射电镜(HRTEM)、紫外-可见漫反射光谱(DRS)、X射线光电子能谱(XPS)、N2吸附-脱附等,对实验所得产物的组成、结构及光学性质等进行表征。以染料罗丹明B(Rh B)水溶液和气态乙醛作为降解对象,采用BiOI、ZnO/BiOI和ZnO微纳材料作为光催化剂,通过对BiOI、ZnO/BiOI和ZnO微纳材料在可见光下光催化降解染料罗丹明B(Rh B)水溶液和气态乙醛,结果表明多孔微纳材料的ZnO/BiOI具有更高的降解效率,实验表明多孔微纳材料的ZnO/BiOI具有更高的氧空位浓度,因此使其催化活性增强,讨论了其可能的催化活性机理。
