Abstract:
This talk will address recent progress in the design of zeolite and metal oxide catalysts. A common objective of zeolite catalyst design is to overcome the inherent mass transport limitations of nanopores; however, the complex pathways of zeolite crystallization make it difficult to control their physicochemical properties. In this talk, I will highlight several methods to tailor zeolite crystal size, morphology, and composition in ways that reduce diffusion limitations and/or control acid siting, thereby enabling the design of catalysts with superior performance compared to materials obtained by conventional synthesis routes. Our research has explored methods of structure direction employing organics, inorganics, and combinations thereof to reduce synthesis times and tailor physicochemical properties. Additional studies of zeolite synthesis have shown how heteroatoms can be integrated in both conventional and hierarchical zeolites to enhance catalyst performance.4 Among the hierarchical zeolites we have recently synthesized are self-pillared pentasils that exhibit four-fold increases in both catalyst lifetime and total turnovers; and a new class of catalysts, referred to as finned zeolites, which are prepared by seeded growth to introduce fin-like protrusions with identical crystallographic registry as the interior crystal. The second part of the talk will focus on metal oxides where we have demonstrated how the use of molten salts can tailor crystal habit to yield structured catalysts with high index facets not easily obtained by conventional synthesis techniques. Advances in the design of mixed metal oxides using molten salts have led to the discovery of exceptional and highly durable catalysts for the oxidative coupling of methane reaction.
