▎ 摘　　要

The reduced graphene oxide (RGO) was prepared by the reduction of graphite oxide (GO) under alkaline conditions. 4-(N,N-Diphenylamine) benzyl alcohol functionalized graphene (TPACH(2)OH-RGO) were formed by stirring the mixture of TPACH(2)OH and RGO at room temperature. Density functional method (DFT) studies show that hydrogen bond is present between TPACH(2)OH and RGO in TPACH(2)OH-RGO. The structure and photoelectric properties of TPACH(2)OH-RGO conjugate were investigated by using ultraviolet-visible spectra (UV-vis), Raman spectra (Raman), fluorescence spectra (Fl), atomic force microscopy (AFM), transmission electron microscopy (TEM) and electrochemical method. The TPACH(2)OH-RGO conjugate was employed as a photocatalyst for H-2 generation from water under ultraviolet-visible light illumination. The experiment results indicated that electron transfer occurred from the excited-state of TPACH(2)OH to RGO. When the mass ratio of TPACH(2)OH to RGO is 4/3, the total amount of H-2 evolved from the TPACH(2)OH-RGO system at pH 6 after 6 h irradiation was 35.0 mu mol, which is higher than that produced from the RGO (20.4 mu mol).
