Fabrication of Ag-InVO₄ Thin Films and Photocatalytic Degradation of Methylene Blue under Visible Light Irradiation

Abstract:

InVO4 films were supported on glass springs via a sol-gel method. Ultrafine Ag nanoparticles, with a particle size of 5~10nm, were deposited on the surface of InVO4 films by a photoreduction process. XRD results revealed that high temperature phase of InVO4 (orthorhombic phase) could be obtained at a relatively low temperature (<500°C). The surface of InVO4 films was rough with numerous small grooves and edges. The visible light induced photocatalytic activity of InVO4 films increased by deposition of Ag nanoparticles. Under visible light irradiation, the excited electrons in conduction band of InVO4 could be trapped by small Ag particles, thus limiting the recombination of photogenerated electron-hole pairs.
