One of the important procedures to enhance the activity of semiconductors as a catalyst is the fabrication of Ag-based semiconductors with a large bandgap energy. Here, a novel Ag/b-Ag2WO4/ V3O4/g-C3N4 heterojunction photocatalyst was synthesized by a solvothermal method. The heterojunction structure was characterized by FT-IR spectroscopy, DRS, FE-SEM, XRD, PL, and EDS techniques. The photo-ability of V3O4, V3O4/g-C3N4, and Ag/b-g2WO4/V3O4/g-C3N4 toward the actuation of C(OH)–H bond was investigated using a visible lamp. The prepared photocatalyst illustrated impressive activity compared to pure V3O4 and V3O4/g-C3N4, which was 67% under aerobic environments due to the considerable separation of the photogenerated charge pairs and enhanced active site safter the incorporation of nanoparticles. Accordingly, this catalyst should be introduced as a qualified photocatalyst, because of its activity, selectivity, and stability.
