Oxidation of cyclohexane over Bi-incorporated MCM-41 mesoporous molecular sieve catalyst with oxygen as oxidant

Bismuth-incorporated MCM-41, which was directly synthesized under strongly acidic conditions and characterized, for the first time. by XRD, UV-vis and Raman spectroscopy, was used as catalyst for the oxidation of cyclohexane without organic solvent using O-2 as oxidant, and the results of reaction indicate that Bi-MCM-41 is a very stable and efficient catalyst.
