电纺丝合成树枝状Ag-TiO2复合材料及光催化降解有机物

摘要

TiO2 nanofibers were synthesized by electrospinning technique and used as the template to fabricate branched Ag-TiO2 composite. The as-prepared Ag-TiO2 composites were characterized by X-ray diffraction and electron microscopy analysis techniques. The photocatalytic activities of as-prepared branched Ag-TiO2 composite were measured with the degradation of active methylene blue( MB). Results show that the as-prepared branched Ag-TiO2 composite exhibited higher photocatalytic activity in comparison with TiO2 nanofibers and commercial TiO2 P25.%通过高压电纺丝方法合成TiO2纳米纤维,以此为模板构建树枝状Ag-TiO2复合材料.采用X射线衍射与扫描电镜对该材料进行结构与形貌表征.与商品化的TiO2( P25)及TiO2纳米纤维相比,该复合材料在亚甲基蓝的光催化降解过程中表现出更优异的催化性能.
