Abstract
In this research, Synthesis of graphene oxide was done by Hummer method, Acid functional groups of graphene oxide through covalent bonding was functionalized by thiamine and was synthesized GO-VB1 with high dispersion in aqueous solvent .Then the catalyst be detected by FT-IR, FE-SEM, XRD, EDS, AFM, TGA. GO-VB1 was used in the synthesis of derivatives benzimidazole. The reaction in the presence of new and green nanocatalyst with good yields and short periods of time at ambient temperature and the solvent is ethanol green Keywords: Graphene oxide, GO-VB1, thiamine, benzimidazole
