英文摘要： This project involves study of magnetic mesoporous materials functionalized with copper complex and their applications in the catalysis of the direct hydroxylation of benzene to phenol by hydrogen peroxide. In the studies, following investigations will be performed: Design, synthesis and characterization of ligands bearing propyltriethoxysilane and their copper complexes; Preparation and characterization of the magnetic mesoporous materials into which the copper complex and magnetic nanoparticles coated with silica gel (Fe3O4@nSiO2) are chemically incorporated using periodic mesoporous organosilica (PMO) method in which tetraethyl orthosilicate (TEOS) is used as silica source and cetyltrimethylammoniumbromide (CTAB) as structure-directing template; Establishment of the correlation between the synthetic conditions and physichemical properties (eg. introducing rate of metal active site, mesopore diameter, BET surface area, total pore volume) of the magnetic mesoporous materials; Evaluation of the catalytic activity of the magnetic mesoporous materials in the direct hydroxylation of benzene into phenol. It is hoped that the structure-activity relationship between the structure and catalytic properties of the magnetic mesoporous materials functionalized with copper complex could be established and the reaction mecha
