Abstract

Mesoporous molecular sieve containing cobalt(CoMCM-41) was synthesized by two-step hydrothermal method.The synthesized CoMCM-41 was characterized by XRD,FT-IR,BET,BJH,and TPR.The results show that the specific surface area is more than 500 m~(2)/g,pore size from 3.5 to(4.0) nm, and the particle diameter from 20 to 40 nm.Calcinated at 550 ℃,the template can be removed but the pore structrue is not influenced.
