Catalytic Applications of Mesoporous Metallosilicate Molecular Sieves and Method for Their Preparation

IntroductionCatalysis of larger molecules would proceed more quickly with larger pores that would allow for more flux into and out of the pores. In addition, one of the most important methods for converting hydrocarbons to useful industrial chemical, intermediates, and pharmaceuticals is catalytic oxidation. Current oxidation routes result in large...
