Aminopropyl-incorporated mesoporous molecular sieve MCM-41 was post-modified by piperidine. The prepared P-AM-MCM-41 was invesitigated referring to the adsorption of CO_ 2 under temperature-programmed heating conditions, providing with some instruction for its application in the solid-base catalysis.
MCM-41 supporting CuO was prepared in the present research by immobilizing metal ions with organofunctionalized MCM-41 and subsequent ultrasonic washing and calcination.The coordination of Cu(II) with organic functionalized MCM-41 as well as the formation of CuO on the molecular sieve surface during the calcination process were investigated by FTIR and In-situ Drift FTIR.
Salen Mn(III)/MCM-48 catalyst was prepared and characterized by FT-IR,XRD,UV-Vis,and GC.The catalyst was evaluated by the epoxidation of styrene;remarkable activity and enantioselectivity were received.
