Abstract

Ag/BiPbOCl nanosheet composites were successfully prepared by hydrothermal synthesis and photo-reduction. The morphology, microstructure, and optical properties of the as-prepared Ag/BiPbOCl nanosheet composites were characterized using TEM, XRD, and UV-Vis diffuse reflection spectroscopy. The prepared Ag/BiPbOCl nanosheet composites with 0.5 wt% Ag exhibit favorable photocatalytic activity, which is 3.6 times that of BiPbOCl nanosheet. The enhanced photocatalytic properties can be attributed to the inner electromagnetic field, higher visible light response range, excellent conductivity, and lower Fermi level of Ag.

摘要

通过水热合成和光还原成功制备了Ag/BiPbOCl纳米片复合材料。使用透射电子显微镜（TEM）、X射线衍射仪（XRD）和紫外可见漫反射光谱对所制备的Ag/BiPbOCl纳米片复合材料的形貌、微观结构和光学性质进行了表征。所制备的含0.5 wt% Ag的Ag/BiPbOCl纳米片复合材料表现出良好的光催化活性，是BiPbOCl纳米片的3.6倍。光催化性能的增强可归因于内部电磁场、更宽的可见光响应范围、优异的导电性以及Ag的较低费米能级。
