The Preparation of In_xBi_1-xVO₄ Photocatalyst Particles and their Photocatalytic Activity

Abstract:

In_xBi_1-xVO₄ photocatalyst particles were prepared by low temperature solid reaction using nitrate of indium and bismuth and NH₄VO₄ as the starting materials, and followed by the sintering at various temperatures. The as-prepared samples were investigated by X-ray powder diffraction (XRD), and the photocatalytic activity was carried out by the concentration change of methylene blue in the solution after visible light irradiation. The experiment results show that the orthorhombic phase InVO₄ is dominant in the photocatalyst samples prepared at sintering temperature higher than 600°C. In addition, the increase in indium content in the In_xBi_1-xVO₄ particle has greatly improved the photocatalytic activity for decomposition of aqueous methylene blue under visible light irradiation.
