▎ 摘　　要

A novel composite of In2O3 nanorods (INR) hybridized with reduced graphene oxide (RGO) was fabricated by a facile UV-assisted photoreduction method. The as-prepared samples were systematically characterized by X-ray diffraction, scanning electron microscopy, transmission electron microscopy, Raman spectroscopy, X-ray photoelectron spectroscopy and UV-vis diffuse reflectance spectroscopy. The one-dimensional INR with high surface-to-volume ratio anchored on the surface of RGO homogeneously, resulting in a nice interfacial contact between INR and RGO. The photocatalytic activities of the INR-RGO composites were investigated for 4-chlorophenol (4-CP) degradation under UV-vis or visible light irradiation. The photodegradation yield of the optimized photocatalyst reached 91.6%, which was about 1.9 times as high as that of INR under visible light irradiation (>400 nm). The enhanced photocatalytic activity of the INR-RGO composites can be ascribed to the efficient interfacial charge transfer from INR to RGO, which resulted in the prolonged lifetime of the photoinduced charge carriers.
