中文摘要mesoporous sba-15 materials modified with pw or w active species as catalysts for the epoxidation of olefins with h2o2
英文摘要five catalysts containing pw or w active species that anchored onto aminosilylated mesoporous silica sba-15 by a post-grafting route were prepared and the resulting pw or w/aptes/sba-15 hybrid materials were characterized by xrd, n-2 adsorption/desorption, surface area analysis, tem, ft-ir, and icp (inductively coupled plasma atomic emission spectroscopy). the names of these catalysts have been abbreviated as sba-15m-a, sba-15m-b, sba-15m-c, sba-15m-d, and sba-15m-e according to the different active species. the pw or w active species were highly dispersed in the channels of the modified mesoporous materials. the interaction between pw or w species and amino groups grafted on the channel surface of sba-15 led to the immobilization of pw or w species. their catalytic activity in the epoxidation of cyclooctene with h2o2 as oxidant was investigated. among them, sba-15m-a showed the best performance, with 98.9% conversion and 98.4% selectivity. the catalyst could be reused for six times with a little decrease in activity.
