Abstract：

Improving　electrocatalyst　performance　is　key　to　the　large-scale　application　of　fuel　cells.　Here,　we　constructed　non-homogeneous　AuPd　alloy　nanoparticles　with　excellent　electrocatalytic　activity　based　on　the　localized　surface　plasmon　resonance　(LSPR)　effect　of　Au　nanoparticles　for　the　first　time.　The　mass　activity　and　specific　activity　of　the　non-homogeneous　AuPd　alloy　for　ethanol　oxidation　reaction　can　reach　18.14　A/mgPd　and　20.28　mA　cm−2,　respectively,　10.67　and　3.75　times　higher　than　that　of　commercial　Pd/C.　Experimental　characterizations　and　theoretical　simulations　show　that　Pd　precursor　is　reduced　and　deposited　on　the　surface　of　Au　NPs,　and　the　localized　temperature　field　drives　the　atomic　interdiffusion.　Finite　element　simulation　results　indicate　a　large　temperature　gradient　around　the　laser-irradiated　Au　NPs,　and　the　effective　reduction　of　the　Pd　precursor　is　confined　to　the　2.5　nm　thick　shell　region.　This　work　demonstrates　the　heterogeneous　nucleation　and　growth　of　nanocrystals　driven　by　LSPR,　providing　a　promising　strategy　for　the　rational　design　of　bimetal　nanoparticles.　©　2023
