Fast Synthesis of Ag_3PO_4 Cube Microcrystals and Its High Visible-Light-Driven Photocatalytic Activities

摘要

Ag_3PO_4 photocatalyst was successfully synthesized via a aqueous precipitation process using AgNO_3, NH_3·H_2O and NH_4H_2PO_4 as raw materials, and characterized by X-ray diffraction(XRD)，solid- UV-Vis and FE-SEM techniques. Photodegradation of Methylene blue solution, Rhodamine B，was studied with Ag_3PO_4 under experiment light recourse of metal halide lamp. The XRD result showed that the sample Ag_3PO_4 synthesized in a high purity belongs to tetragonal. And the sample has a strong absorption between 200 nm and 400 nm analysized by UV-Vis. The photodegradation experiment showed that Methylene blue solution, Rhodamine B was more easily photodegradated with Ag_3PO_4 and light recourse was metal halide lamp.
