High-Index Faceted Platinum Nanocrystals Supported on Carbon Black as Highly Efficient Catalysts for Ethanol Electrooxidation

Platinum nanocrystals on carbon black were synthesized by an electrochemical square‐wave potential method (HIF‐Pt/C, see picture). The nanocrystals have high‐index facets and a high density of atomic steps. Thanks to this high density, the catalysts exhibit at least twice the activity and selectivit...

Description
Summary:Platinum nanocrystals on carbon black were synthesized by an electrochemical square‐wave potential method (HIF‐Pt/C, see picture). The nanocrystals have high‐index facets and a high density of atomic steps. Thanks to this high density, the catalysts exhibit at least twice the activity and selectivity of commercial Pt/C catalysts for ethanol electrooxidation into CO2.
