Pt₃Sn nanoparticles enriched with SnO₂/Pt₃Sn interfaces for highly efficient alcohol electrooxidation.

ABSTRACT: Pt₃Sn nanoparticles (NPs) enriched with Pt₃Sn/ultra-small SnO₂ interfaces (Pt₃Sn@u-SnO₂/NG) were synthesized through a thermal treatment of Pt₂Sn/NG in a H₂ atmosphere, followed by annealing under H₂ and air conditions. The unique structure of Pt₃Sn NPs enriched with Pt₃Sn/SnO₂ interfaces was observed on the Pt₃Sn@u-SnO₂/NG catalyst based on HRTEM. The optimized Pt₃Sn@u-SnO₂/NG catalyst achieves high catalytic activity with an ethanol oxidation reaction (EOR) activity of 366 mA mg_Pt ^-1 and a methanol oxidation reaction (MOR) activity of 503 mA mg_Pt ^-1 at the potential of 0.7 V, which
