Platinum alloy bimetallic catalysts for fuel cells

Bimetallic alloy catalysts of Pt-Pd, Pt-Ru, Pd-Ru and Pd-Ag were prepared at 5 and 10 wt. % loading at different atomic compositions on carbon supports. The catalysts weloe subjected to a heat treatment at 923 K in hydrogen atmosphere. The catalysts were characterised by XRD and clectroche ical techniques. Porous carbon electrodes were fabricated and the electrocatalytic activity towards ele trooxidation of methanol, formaldehyde and ethylene glycol in acid and alkaline solutions were evaluated
