Preparation of Ag3(PO4)x(VO4)1-x photocatalyst and its Photocatalytic Performance |
초록 |
Ag3(PO4)x(VO4)1-x was prepared by precipitation method and evaluated for the decomposition of Orange II dye under visible light irradiation(λ>530nm). UV-vis DRS showed that Ag3(PO4)x(VO4)1-x had similar visible light absorptivity to Ag3VO4. X-ray diffraction indicated that Ag3(PO4)x(VO4)1-x was a single-phase compound. XRD pattern of Ag3(PO4)x(VO4)1-x was very similar to the XRD pattern of Ag3VO4. It was due to Ag3VO4 was more stable than Ag3PO4. Moreover, right shifted XRD pattern means that relatively small PO43- ions penetrated into Ag3VO4 lattice. The photo activities of the synthesized samples were evaluated by photocatalytic decomposition of the Orange II dye. Ag3(PO4)x(VO4)1-x had better photocatalytic activity than Ag3PO4 and Ag3VO4 under λ >530nm irradiation, where Ag3PO4 rarely absorbed the light.
