The construction of efficient photocatalysts for environmental remediation has attracted a great deal of attention in recent years. In this study, a novel Ag3VO4/WO3 heterojunction photocatalyst has been successfully prepared via a hydrothermal process and a facile precipitation reaction. Under visible light irradiation, the hybrid materials could significantly enhance photocatalytic activity for the degradation of tetracycline (TC) in comparison with single Ag3VO4 and WO3. Within 30 min, 71.2% TC could be photodegraded by the optimum sample (10% A/W), which was about 3.1 times and 4.6 times higher than that of the individual Ag3VO4 and WO3, respectively. Based on the active species trapping experiments and ESR, the photocatalytic oxidation mechanism of the Ag3VO4/WO3 composite was also discussed. It can be assumed that the enhancement of the photocatalytic activity was attributed to the heterojunction which could widely accelerate the separation of photogenerated electron-hole pairs. In general, WO3 hybridized with Ag3VO4 will also efficiently address the problem of low photocatalytic activity.
