Effect of Co-doping Under Microwave Irradiation on Structural Performance of MCM-41 Molecular Sieve

Co-doped MCM-41 mesoporous molecular sieve was successfully synthesized by using cetyltrimethyl ammonium bromide(CTAB) as a template with microwave irradiation method.The calcined samples were characterized by means of XRD,FT-IR,ICP,TEM and N2 physical adsorption,respectively.The results show that the synthesized samples are calcined at 550 ℃ for 10 h,the template can effectively be removed,Co-doped MCM-41 mesoporous molecular sieve is gained,the Co-MCM-41 mesoporous molecular sieve has larger specific surface area and a uniform pore distribution comparing with the pure silica MCM-41mesoporous molecular sieve.
