▎ 摘　　要

In this research, main emphasis has been placed on the oxidizing properties of graphene oxide (GO) and hypervalent organoiodine (III) (HVI) and their oxidizing effect in GO-HVI. GO-HVI as a metal-free, environment-friendly, recyclable and efficient heterogeneous reagent was synthesized and completely characterized by Fourier transform infrared spectroscopy (FT-IR), energy dispersive X-ray (EDX), field emission scanning electron microscopy (FE-SEM), X-ray diffraction, and atomic force microscopy (AFM). The synthesized GO-HVI was used to achieve an effective and selective method for oxidation of various alcohols. All substituted alcohols were oxidized in good to excellent yields under mild conditions at room temperature. The oxidizing ability of GO-HVI was higher in comparison with starting GO and HVI. This GO-HVI have great stability and could be recycled six times without noteworthy loss of activity.
