Popis: A magnetically separable photocatalyst silver vanadates@SiO2/Fe3O4 was prepared by hydrothermal process. The prepared sample was composed of mixed phases of a–Ag3VO4 and Ag4V2O4, and the main phase was a–Ag3VO4. The bandgap of the synthesized sample was 2.2 eV. In the degradation of methyl orange (MO) solution under the visible light (l>420 nm), the silver vanadates@SiO2/Fe3O4 showed high photocatalytic activity in two-cycle photocatalytic test.
