Preparation of Sphere-Like Ag-Ag_3PO_4 Visible-Light Plasmonic Photocatalysts and Application in Decomposition of Rhodamine B

The plasmonic photocatalyst of Ag-Ag3PO4sub-microstructures were obtained by a direct precipitation and subsequently visible-light-induced process. The products were characterized by electron microscopy, X-ray powder diffraction, and UV-vis diffusive reflectance spectrums, respectively. The photocatalytic activity of sphere-like Ag-Ag3PO4sub-microstructures for rhodamine B was investigated. The kinetic data and cycling degradation experiments indicate that the sphere-like Ag-Ag3PO4sub-microstructures was catalytically more active than sphere-like Ag3PO4sub-microstructures. Herein, the sphere-like Ag-Ag3PO4sub-microstructures show potential application in the feild of environmental remediation.
