Preparation and Photocatalytic Properties of γ-Bi2O3/TiO2 Composite Fibers
Source abstract
Abstract
采用静电纺丝技术与溶剂热法相结合制备了γ-Bi 2 O 3 /TiO 2 复合纤维光催化材料. 利用X射线衍射(XRD)、扫描电镜(SEM)、电子能谱(EDS)、透射电镜(TEM)、高分辨透射电镜(HRTEM)和紫外–可见吸收光谱(UV-Vis)等分析测试手段对材料进行了表征, 并以罗丹明Ｂ(RB)的脱色降解为模式反应, 考察了材料的可见光催化性能. 结果表明: γ-Bi 2 O 3 纳米片均匀地生长在TiO 2 纤维上, 形成了具有异质结构的γ-Bi 2 O 3 /TiO 2 复合纤维光催化材料, 其光谱响应范围拓宽至可见光区, 有利于TiO 2 光生电子和空穴的分离, 增强了体系的量子效率. 与纯TiO 2 纤维相比可见光催化活性明显提高, 对RB的脱色率达87.8%.
