Preparation and Photocatalytic Properties of ZnS Hollow Microspheres

Keywords： solvothermal method , hollow microsphere , ZnS , photocatalysis

采用简单的一步溶剂热法合成了ZnS空心微球.利用X射线衍射(XRD)、扫描电子显微镜(SEM)、高分辨透射电子显微镜(HRTEM)、X射线光电子能谱(XPS)和紫外可见吸收光谱(UV-vis)等测试手段对其形貌、结构和光学性质进行了分析,并以罗丹明B(RhB)为模型污染物研究了样品的光催化性能.结果表明:样品为纯度较高的立方闪锌矿型ZnS微球,且球体由纳米级小微粒组装而成;在降解RhB的光催化研究中,以乙醇-水为溶剂合成的ZnS微球光催化性能较优.
