Cu/SBA-IS mesoporous material synthesized by ions exchanging method.

Abstract

Cu-containing SBA-I5 mesoporous (Cu/SBA-I5) material has been prepared based on silica SBA-i5 solid exchanged with Cu(l1)-ion solution under appropriate condition. The obtained samples Were characterized by atomic absorption spectrometry (AAS). powder X-ray diffraction (XRD) and nitrogen  adsorption/desorption measurement. The investigated results show that the prepared samples have highly ordered hexagonal mesostructure with large specific surface area and uniform mesopore size distribution. Catalytic performance of the Cu/SBA-I5 material is investigated through the oxidation of red phenol by hydrogen peroxide as oxidizing agent. The Cu/SBA-15 catalyst exhibited an excellent catalytic activity.
