Abstract
Cu-MCM-41 mesoporous molecular sieves were synthesized by a novel microwave irradiation method with cetyltrimethyl ammonium bromide as a template,and inorganic salt sodium silicate and copper chloride as raw materials.The structure,morphology,crystalline size,specific surface area and pore size distribution of the synthesized samples were characterized by powder X-ray Diffraction(XRD),Transmission Electron Microscopy(TEM) and N2 physical adsorption-desorption technique,respectively.The experimental results show that Cu-MCM-41 mesoporous molecular sieves with different pore sizes can be successfully synthesized by microwave irradiation method.The specific surface area and pore volume of the synthesized Cu-MCM-41 mesoporous molecular sieves decrease,and the mesoporous ordering of the samples becomes poor with the increasing of the molar ratio of CuO to SiO2 in the feedstock.
