Abstract

Platinum-tin (Pt/Sn) binary nanoparticles are active electrocatalysts for the ethanol oxidation reaction (EOR), but inactive for splitting the C-C bond of ethanol to CO₂. Here we studied detailed structure properties of Pt/Sn catalysts for the EOR, especially CO₂ generation in situ using a CO₂ microelectrode. We found that composition and crystalline structure of the tin element played important roles in the CO₂ generation: non-alloyed Pt₄₆-(SnO₂)₅₄ core-shell particles demonstrated a strong capability for C-C bond breaking of ethanol than pure Pt and intermetallic Pt/Sn, showing 4.1 times higher CO ₂ peak partial pressure generated from EOR than commercial Pt/C.
