Abstract:
Much attention has been paid to the use of the new mesoporous material, MCM-41,as catalyst or catalyst support[1,2]. Recently, we focus our study on the design of catalytically active sites such as vanadium species inside the mesopore of MCM-41. V-MCM-41 is generally synthesized by direct hydrothermal method in the literature, but a large part of vanadium sites seems difficult to be accessed during the catalytic reactions by this method. We have developed a novel method to introduce vanadium species by a template-ion exchange (TIE) method, i.e., by exchanging the template cation in the uncalcined MCM-41 with VO2+ ion in aqueous solution. Here, the results of the characterizations of such synthesized V-MCM-41 and its catalytic properties in oxidative dehydrogenation of propane are described.
