Synthesis with Atomic Scale Control for Highly Selective Catalysts


EMSL Project ID
48174

Abstract

The proposed work is focused on catalyst design for the conversion of biomass to fuels and chemicals. Specifically, we propose a rational design methodology aimed at controlling the catalyst synthesis to prepare catalysts with defined structures on the atomic scale. The kinetic measurement on the defined catalyst structures will allow us to build structure activity relations and with complementary theoretical calculations, we will guide the synthesis of more active and selective catalysts. The controlled synthesis of colloidal metal nanoparticles will be achieved through the use of microfluidics and in situ time resolved characterization techniques which will enable an atomic view of the synthesis mechanisms. The fundamental understanding of the synthesis mechanisms will allow us to manipulate the reaction conditions to synthesize the nanoparticles with the required size, shape and composition to maximize the catalyst activity and selectivity.
