     a versatile, solvent free aerobic alcohol oxidation system has been established in the presence of benzaldehyde based on a heterogenous cobalt catalyst supported on nanoshell carbon (co/nsc), which was prepared through the pyrolysis of a mixture of co(ii) phthalocyanine and phenol resin. the established system features equal efficiency toward both benzylic alcohols and aliphatic alcohols. the nanoshell carbon has been demonstrated to be a better supporting material for the present reaction than some other carbon materials, e.g., activated carbon. mechanistic studies suggest that co/nsc can catalyze the formation of oxidative intermediate peroxybenzoic acid as efficiently as homogeneous cobalt catalyst, and moreover, suppress the undesired baeyer–villiger side reaction. co/nsc also exhibits good reusability, i.e., it can be reused for at least 10 times without significant loss of performance.
