束状纳米结构SnS薄膜的制备及其光催化性能

Preparation of SnS Films with Bundle-Like Nanostructure and Their Photocatalytic Performance

采用化学浴沉积方法,分别以氟掺杂氧化锡导电玻璃(FTO)和普通玻璃为衬底,在70℃下制备具有束状纳米结构的SnS薄膜.通过研究反应时间对束状纳米结构SnS薄膜的影响,提出束状纳米结构SnS薄膜可能的成膜机制,并测试束状纳米结构SnS薄膜对罗丹明-B的光催化降解性能.结果表明,生长在FTO衬底上的束状纳米结构SnS薄膜具有更优异的光催化性能.

The SnS thin films with bundle-like nanostructure were prepared by chemical bath deposition at 70℃,using fluorine-doped tin oxide conductive glass(FTO)and ordinary glass as substrates,respectively.By studying the effect of reaction time on the bundle-like nanostructure SnS thin films,we proposed the possible forming mechanism of the bundle-like nanostructure SnS thin films,and tested the photocatalytic degradation performance of the bundle-like nanostructure SnS thin films on rhodamine B.The results show that the SnS thin film with bundle-like nanostructure grown on FTO substrate has better photocatalytic performance.
