Hydrothermal synthesis of g-C3N4/Ag2MoO4 nanocomposites for improved visible light photocatalytic performance

Novel graphitic carbon nitride/silver molybdat (g-C3N4/Ag2MoO4) nanocomposites with different weight contents of g-C3N4 have been successfully synthesized by a hydrothermal synthesis method. The as-obtained nanocomposites were measured by X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), and UV–vis diffuse reflectance spectroscopy (UV–vis DRS). The photocatalytic performance of g-C3N4/Ag2MoO4 nanocomposites for the photodegradation of RhB was better than that of the pristine g-C3N4 and Ag2MoO4 under visible light irradiation. The experiment results showed that the 80% g-C3N4/Ag2MoO4 nanocomposites exhibited the optimal photocatalytic performance. The probable mechanism of the improved photocatalytic performance by synergy effect between g-C3N4 and Ag2MoO4 was investigated systematically.
