In this paper, WO3/Ag3VO4 photocatalysts were successfully synthesised at various Ag3VO4/WO3 mole ratiosof5, 10, 15, and 20%(WA-x). Ultraviolet-visiblediffuse reflectance spectra (UV-Vis-DRS) indicated that the adsorption capacity of WA-10 (10% Ag3VO4/WO3 mole ratios) under visible light was higher than that of other materials. The photocatalytic properties of obtained materials were investigated by degradation of the antibiotic AMX under visible light irradiation. The degradation conversation of AMX had gotten to about 79.86% in WA-10 after a reaction of three hours. WO3/Ag3VO4 materials were highly active than WO3 and Ag3VO4 with an increase in photocatalytic activity of WO3/Ag3VO4 that can be attributed to the efficient separation of photogenerated electron-hole pairs.
