Abstract: Zinc modified MCM41 was prepared by hydrothermal synthesis method followed by silylation of 3-amin-opropyltrimethoxysilane and ZnC12 treatment. N2 BET and IR indicated that zinc was introduced into the mesopores of MCM41. This material can be employed to catalyze copolymerization of ethylene oxide and carbon dioxide. -
