Abstract

Ultra-small core–shell structured Au–Pt nanoparticles with discrete Pt shells can realize the oxidation of formic acid in the dehydrogenation pathway.

Highlights

  • It is well known that the catalytic performance of the electrocatalysts is highly dependent on their composition, structure and morphology.[1,2,3] the same electrocatalysts may show different catalytic performance for different reactions

  • Performance of USCSD Au61.2@Au27.3Pt11.5 NP/C catalysts (USCSD Au61.2@Au27.3Pt11.5 NPs loaded on carbon black) as well as commercial Pt/C catalysts and the USCS Au38.4@Au9.3Pt52.3-NP/C catalysts towards the formic acid oxidation reaction (FAOR) were investigated in acidic media for comparison

  • A series of concentration of Pt(II) ions were investigated in the ultralow concentration range between 1.46 and 2.43 μM for synthesis of USCSD Au-Pt NPs on the basis of our previous recipe.[4]
