Using prepared heterogeneous catalyst GO-HSO , benzimidazole synthesis was carried out by means of reacting diamine and aldehyde at room temperature in solvent free condition. The catalyst GO-HSO showed tremendous catalytic activity in selective synthesis of benzimidazole, as a result 100 % conversion of reactants and up to 89.0 % yield of respective benzimidazole was achieved using 0.1 mg of catalyst in very short reaction duration. The GO-HSO catalyst was separated from the reaction mixture by simple ﬁltration process at the end of reaction and reused for six successive cycles without noteworthy loss of catalytic activity and selectivity. Key advantageous of this protocol is high yield, low cost,
