Preparation and Photocatalytic Properties of Titania Nanowires Loaded with Ag Nanoparticles

利用水热合成法,制备出了二氧化钛纳米线,通过葡萄糖还原Ag(NH3)+2,在制备出的二氧化钛纳米线表面负载了 Ag纳米颗粒.利用透射电镜(TEM)、高分辨透射电镜(HRTEM)、X射线光电子能谱(XPS)和紫外-可见光谱(UV-Vis)对产物进行了表征.结果表明:该Ag/TiO2纳米线在可见光区域表现出较强的吸收性能.测试了样品降解酸性红3R溶液的活性.结果表明,TiO2纳米线表面负载Ag纳米颗粒对提高其光催化性能具有积极的作用.
