Preparation and Property of W-MCM-41 Mesoporous Catalysts in an Open System
Abstract:
W-MCM-41 mesoporous catalysts were successfully synthesized in an open system with tetraethyl orthosilicate(TEOS) as silica precursor,sodium tungstate as tungsten precursor,and cetyltrimethylammonium bromide(CTAB) as structure-directing reagent.The samples were characterized by means of various techniques and their catalytic properties for the oxidation of cyclohexene were studied.The effects of Si/W molar ratios on the structure and catalytic properties were investigated in details.The results show that the prepared samples retained the ordered mesoporous structure of MCM-41 and exhibited high catalytic properties.The sample synthesized with n(Si)/n(W)=30 exhibited better catalytic property than others.
