Full use of factors promoting catalytic performance of chitosan supported manganese porphyrin

Abstract In order to make full use of the impact of internal and external factors on the performance of title catalyst for ethyl benzene oxidation, the key internal influencing factors on the catalytic performance were modulated by coordinating and grafting manganese porphyrin to mesoporous and macr...
