Abstract
A nanomaterial catalyst of azo-bridged Cu(II) porphyrin polymer (CuII-APP) was synthesized and characterized by scanning electron microscopy, transmission electron microscopy and N2 adsorption measurement. CuII-APP had a nanoporous structure, with the particle size of about 30nm. Owing to the special structure, CuII-APP acted as an efficient heterogeneous catalyst for selective oxidation of cyclohexylbenzene into cyclohexylbenzene-1-hydroperoxide. When N-hydroxyphthalimide was used as co-catalyst, this binary catalyst system showed an obvious synergic effect. After being recovered and reused, CuII-APP and NHPI still had high catalytic activities.
