development of anode electrocatalysts for direct formic acid fuel cells

In this work, for the development of platinum-based nanostructured catalysts for use in formic acid fuel cells, a hybrid substrate of reduced graphene oxide with nanocarbon synthesized and platinum nanoparticles reduced by sodium borohydride on the surface of this hybrid substrate and the catalyst powder of rgo50%-nc50%/pt was synthesized. physicochemical studies indicate good dispersion with high density of pt nanoparticles on the surface of the hybrid substrate. electrochemical studies also showed that the rgo50%-nc50%/pt hybrid catalyst has better electro-catalytic behavior for the oxidation of formic acid in an acidic environment compared to the rgo/pt and nc/pt catalysts.
