摘要/Abstract

摘要：

借助棉花纤维模板, 采用两步法制备了Ag⁺/Ag/ZnO多孔纳米结构纤维材料, 并利用X射线衍射(XRD)、 X射线光电子能谱(XPS)、扫描电子显微镜(SEM)和紫外-可见光谱(UV-Vis)等对其进行了表征. 以亚甲基蓝(MB)的脱色降解为模型反应, 考察了银修饰量(摩尔分数, 0~1.50%)对ZnO纳米结构纤维材料光催化性能的影响. 结果表明, 利用模板辅助的两步法制备了Ag⁺-Ag共修饰的ZnO多孔纳米结构纤维材料Ag⁺/Ag/ZnO, Ag⁺和Ag通过改变ZnO的晶胞结构、光吸收特性及形貌等影响其光催化性能; 在可见光条件下, Ag⁺/Ag/ZnO的催化性能优于纯ZnO, 且与修饰量有关.

关键词: Ag+/Ag/ZnO, 多孔纳米结构纤维材料, 模板辅助两步法, 光催化性能

Abstract:

Ag⁺/Ag/ZnO porous nano-structured fiber materials were prepared by the template-assisted two-steps method and characterized by thermogravimetric analysis(TG), X-ray diffraction(XRD), X-ray photoelectron spectroscopy(XPS), scanning electron microscopy(SEM) and UV-Vis spectroscopy(UV-Vis) techniques. The effect of modified silver amount(molar fraction, 0—1.5%) on the photocatalytic property of ZnO materials was studied by the degradation of methylene blue(MB) as the model reaction. The results show that the Ag⁺-Ag co-modified ZnO porous nano-structured fiber materials are successfully prepared via the template-assisted two-steps method and the Ag⁺-Ag co-modifification affects the photocatalytic performance of ZnO materials by affecting its cell structure and light adsorption property and morphology. Under the irradiation of visible light, the Ag⁺/Ag/ZnO porous nano-structured fiber materials showed better catalytic performance than pure ZnO and the catalytic perfrmace of Ag⁺/Ag/ZnO is related to the modified amount of Ag⁺-Ag. In this paper, the way of Ag⁺ and Ag for improving photocatalytic performance of the ZnO materials was discussed. And the obtained results are helpful to understand the photocatalytic phenomena and mechanisms on the multi-structured material.
