▎ 摘  要

Cu2O/reduced graphene oxide/TiO2(Cu2O/rGO/TiO2) photocatalyst was synthesized under ultrasonic irradiation. The nanomaterial was identified by scanning electron microscopy (SEM), transmission electron microscopy (TEM), X-ray diffraction (XRD), Raman spectroscopy, X-ray photoelectron spectroscopy (XPS), Fourier transform infrared (FT-IR) spectroscopy, UV-vis absorption, and inductively coupled plasma optical emission spectroscopy (ICP-OES). The Cu2O/rGO/TiO(2)photocatalyst was utilized in "click" reaction for the preparation of 1,4-disubstituted 1,2,3-triazoles via one pot multicomponent reaction of benzyl halide or epoxide derivatives with alkynes in presence of NaN(3)and triethylamine under visible light irradiation. The "click" reaction was performed under mild conditions affording good to excellent yields of the triazole compounds using low catalyst loading in short reaction times. The nanocomposite was recovered and recycled for five successive runs without a major diminution in its catalytic performance.
