Abstract: A series of Ru-doped mesoporous molecular sieves have been synthesized and characterized by XRD, N2 adsorption/desorption, ICP, FT-IR, FE-SEM, and HRTEM. The characterization results reveal the structure of catalyst and the nature of Ru species. The catalytic performance of the synthesized catalysts has been evaluated for the oxidation of cyclohexane under a mild condition t using air as oxidant without any solvent. Catalytic result shows that these catalysts are efficient, and that the behavior of Ru species is different.
