Model electrocatalysts for the oxidation of rechargeable electrofuels – carbon supported Pt nanoparticles prepared in UHV
UHV-prepared Pt nanoparticles on carbon supports serve as model electrocatalysts for studying isopropanol oxidation — part of a rechargeable electrofuel cycle with acetone. Oxidation onset is at 0.3 V_RHE with high acetone selectivity and only trace CO₂ as a side product; no adsorbed CO is observed, and comparison with Pt(111) suggests particle size and low-coordination sites play a minor role.
