Nanochemical Strategies for Propulsion Enhancement

Abstract

A four PI team (PI: Scott Anderson, Utah, co-PIs Anastassia Alexandrova, UCLA, James Dumesic and Manos Mavrikakis, U.Wisc.) developed alloy nanoparticle and sub-nano cluster catalysts for selective alkane dehydrogenation, with the goal of reducing coking tendency in endothermic cooling applications. In each thrust, theory and experiment were combined to predict and evaluate different alloys. Pt-Sn, Pt-Zn, and Pt-Ge alloys all showed promising activity and stability. Unwanted deep dehydrogenation to coke precursors was suppressed, and catalyst activity and lifetime was enhanced.
