Crossley Catalysis and Nanomaterials Group Website

Our research focuses on heterogeneous catalysis and nanometerials synthesis. The overarching approach behind each of our projects is to understand the interaction between the catalyst composition and surface structure with the resulting reactivity for a given reaction of interest. By understanding the reaction intermediates responsible for activity and selectivity, better catalysts may be formulated and utilized for their appropriate applications. Techniques utilized to accomplish this task include catalyst synthesis, detailed characterization both in and ex situ, and reaction kinetics.

 

Our current projects center around two classes of catalysts, zeolites and metals supported on reducible oxides, where we aim to better understanding the reason for their promising catalytic behavior. Current projects address important issues ranging from the production of renewable fuels and chemicals to the activation of hydrocarbons. We also synthesize advanced carbon-based materials for use as catalyst supports and emulsion stabilizers. Please visit our group webpage to find out more.
