Catalytic performance of chromium Schiff base complexes immobilized on mesoporous materials in benzyl alcohol oxidation
A series of chromium (III) Schiff base complexes immobilized on amorphous silica gel (SiO2), MCM-41 and SBA-15 were prepared and use for the selective oxidation of benzyl alcohol (BzOH). The results revealed that the complex immobilized on ordered mesoporous MCM-41 exhibited the highest catalytic performance. Such a significant difference in the catalytic performance of the immobilized complexes could be due to their different inner coordination structures as well as the different local concentration of reactant and objective product around their active sites, which all originated form their different support structures.
