Abstract: Copper doped MCM-41(Cu/MCM-41) was synthesized by using cetyltrimethylammonium bromide as a template,copper nitrate as copper precursor,and ethyl silicate as the silica source via hydro thermal method.Cu/MCM-41 was characterized by XRD,N2 physisorption,UV-Vis,X-ray diffraction and FT-IR.The results indicated that material has uniform hexagonal channels and copper ion highly disperses into silicon framework of the MCM-41 with tetradentation.The catalytic activity of Cu/MCM-41 was studied by oxidation of phenol to benzoquinone.
