Synthesis of WO3/Ag3VO4 photocatalyst with enhanced visible light efficiency photocatalysis

Abstract

WO3/Ag3VO4photocatalyst was synthesized for benefiting the visible region of solar spectrum for degradation of antibiotic pollutant. The prepared catalyst was characterized by using scanning electron microscope (SEM), X-ray diffraction (XRD), infrared spectroscopy (IR) and energy-dispersive X-ray spectroscopy (EDX). The photocatalytic performance of material was evaluated by the photoredution of degradation of Amoxicillin (AMX) antibiotic under visible light. Results show that the obtained WO3/Ag3VO4photocatalyst can significantly enhance photocatalytic activity in comparison with the pure WO3 and Ag3VO4. The enhanced photocatalytic activity of WO3/Ag3VO4 was predominantly attributed to the synergistic effect which increased visible-light absorption and facilitated the efficient separation of photoinduced electrons and holes.
