Bi2Sn2O7改性ZnO微球纳米复合材料的制备及其光催化性能研究
Fabrication of Bismuth Stannate Modified ZnO Microspheres for Enhanced Photocatalytic Activity
利用水热法和水解发制备出Bi2Sn2O7 (BSO)和ZnO微球，将其按照不同比例进行混合，通过煅烧后制备出不同比例的复合材料。利用TEM、UV-Vis 和PL表征方法对材料的形貌和光学性能进行表征。比较不同比例BSO对ZnO光催化性能的影响。结果表明：12.5BSO-ZnO的复合材料表现出最好的光催化性能，这是由于材料中异质结结构的存在使光生电子和空穴达到了有效的分离。
ZnO microspheres synthesized by using a hydrolysis method were modified with different contents of Bi2Sn2O7 (BSO), which was prepared by a hydrothermal method. TEM, UV-Vis and PL were employed to study morphological, optical and photocatalytic properties of the BSO-ZnO heterostructures. Effects of BSO content on photocatalytic activities of the as-prepared samples were also investigated, and the highest photocatalytic efficiency was observed for the 12.5BSO-ZnO sample. Enhanced photocatalytic efficiency was ascribed to an effective separation of the photogenerated electrons and holes, due to the presence of the BSO-ZnO heterojunction.
