| Abstract: The g-C3N4/SnO2 composite had been fabricated by the combination of hydrothermal method and thermal polymerization process in this paper. The crystal structures and morphology of various samples were characterized using XRD, SEM, TEM, FT-IR, and UV-Vis DRS. The results showed that the optical absorption edge of g-C3N4/SnO2 composites with co-effect of heterojunction had an obvious red shift to the longer wavelength in comparison with pure SnO2 and SnO2 nanoparticles were dispersing on the g-C3N4 surface well. The photocatalytic degradation properties of g-C3N4/SnO2 composites on rhodamine B (RhB) were remarkably improved under visible light irradiation, and the degradation rate of optimal 50%-g-C3N4/SnO2 composite was 3.78 times as great as that of pure g-C3N4. |
