摘要

Bimetallic catalysts have replaced monometallic catalysts for a wide range of catalytic applications. Bimetallic catalysts often exhibit enhanced selectivity, stability, and/or activity relative to their corresponding monometallic components. Many different methodologies are used for bimetallic catalysts preparation [1]. However, the typical methods of co-impregnation and successive impregnation have poor control of metalmetal interaction and surface composition. Electroless Deposition (ED) has been used for the preparation of true bimetallic catalysts with controlled, bimetallic surface compositions [2, 3]. We have recently studied platinum-ruthenium bimetallic catalysts that are widely used in fuel cells and bio-mass conversion [4]. My research has focused on the preparation and characterization of both platinum deposited on carbon-supported ruthenium catalysts (Ru@Pt/C) as well as Ru deposited on carbon-supported platinum catalysts (Pt@Ru/C).
