Electrochemical Synthesis of Pd Nanorods and Nanowires on High Surface Area C Supports

Stage: Development

Anisotropic growth of palladium nanoparticles on high surface area carbon supports is encouraged by the choice of surface preparation and electrochemical deposition parameters. The resultant nanorods and nanowires have extremely smooth surfaces, improving their catalytic activity for the oxygen reduction reaction in fuel cells, as well as for other reactions. These ultra-smooth surfaces can be used as-grown, or may be subjected to further processing, such as deposition of monolayers of platinum or gold, to further enhance catalytic activity.  These materials are well suited to heterogeneous catalysis and electrocatalysis, especially at fuel cell electrodes.
