Metal core–shell nanostructures have been extensively studied as one of the most promising electrocatalysts to significantly reduce the loading of the expensive Pt catalyst for fuel cells but it is very challenging to fabricate such a structure to possess proper metal components while making small and uniformly distributed nanoparticles for high catalytic performance. In this work, small and uniformly...
For the first time, herein formic acid is used to reduce precursor for uniformly distributed ultrasmall Pd nanocrystals on graphene as an electrocatalyst towards formic acid oxidation, demonstrating more negative half-wave potential, much higher catalytic current density, lower charge-transfer resistance and better stability than that of the commercial Pd/C catalyst. Except the contribution of the...
