چکیده
|
Cu(ii) complex with l-histidine (his) ligand, immobilized within al-mcm-41, designated as cu(his)2/al-mcm-41 was prepared and characterized by powder x-ray diffraction (xrd), nitrogen adsorption desorption, ftir, uv-vis and chemical analysis techniques. the surface area and pore volume were found to decrease after immobilization of cu(ii) complex on al-mcm-41. it was found that cu(his)2/al-mcm-41 catalyze the oxidation of some alkenes such as norbornene and trans-stilbene with tert-butylhydroperoxide (tbhp) with high activity and selectivity to the corresponding epoxides. it was concluded that the al-mcm-41 nanoreactors is a suitable support for immobilization of biomimetic molecules. particularly significant is that no desorption was observed during the course of reactions
