摘要
采用光还原方式,成功制备了Ag/Ag_2WO_4纳米线。通过扫描电镜(SEM)和透射电镜(TEM)对产品形貌进行观察,通过X-射线衍射(XRD)、紫外可见吸收光谱(UV-Vis)、荧光光谱(PL)等测试技术对样品的晶向组成和光学性能进行了表征,研究了Ag/Ag_2WO_4纳米线的可见光光催化性能。Ag/Ag_2WO_4纳米线与纯Ag_2WO_4纳米线的光催化降解活性相比,在60 min内光催化效率最高可提高47%。
Ag/Ag2WO4 nanowires were successfully prepared by photo-reduction.The morphological features were observed by SEM and TEM.The structural features and optical properties were investigated by XRD,UV-Vis and PL methods.Ag/Ag2WO4 nanowires exhibited higher visible-light-driven photocatalytic activity than pure Ag2WO4,with increased efficiency by up to 47%in 60 min.
