Enhanced Visible Light-Responsive Photocatalytic Properties of Ag/BiPbO2Cl Nanosheet Composites.

Ag/BiPbO2Cl nanosheet composites were successfully prepared by hydrothermal synthesis and photo-reduction. The morphology, microstructure, and optical properties of the as-prepared Ag/BiPbO2Cl nanosheet composites were characterized using TEM, XRD, and UV-Vis diffuse reflection spectroscopy. The prepared Ag/BiPbO2Cl nanosheet composites with 0.5 wt% Ag exhibit favorable photocatalytic activity, which is 3.6 times that of BiPbO2Cl 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.
