Ag+/Ag/ZnO 多孔纳米结构纤维材料的制备及可见光催化性能
Preparation and Visible-light Catalytic Property of Ag+/Ag/ZnO Porous Nano-structured Fiber Materials
摘要
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 photoe-lectron spectroscopy(XPS), scanning electron microscopy(SEM) and UV-Vis spectroscopy(UV-Vis) tech-niques. 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 mate-rials by affecting its cell structure and light adsorption property and morphology. Under the irradiation of visi-ble 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 pa-per, 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.关键词
