Synthesis and structure of silicalite-1/SBA-15 composites prepared by carbon templating and crystallization

Abstract

In many catalytic applications of zeolites, slow diffusion of large molecules and pore blockage are serious limitations toward their efficient usage. Composites containing zeolites and controlled mesoporosity aim to address this problem. We explore three different approaches based on solid phase crystallization and carbon templating to synthesize silicalite-1/SBA-15 composites. Of these three, the method involving a fully developed mesoporous carbon structure offers clear advantages over the other two. The final products are composites, rather than a single phase of fully crystalline mesoporous zeolite.
