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]
