Formic acid-reduced ultrasmall Pd nanocrystals on graphene to provide superior electocatalytic activity and stability toward formic acid oxidation

For the first time, ultrasmall Pd nanocrystals uniformly distributed on graphene (Pd@Graphene) was synthesized using formic acid as a facile regent. Towards formic acid oxidation, comparing with commercial Pd/C, as prepared Pd@Graphene electrocatalyst presents higher intrinsic catalytic activity and better stability, thus holding a great promise as a superior DFAFC anode catalyst.231
