Composition dependent activity of Cu-Pt nanocrystals for electrochemical reduction of CO2

摘要

The Cu-Pt nanocrystal (NC) samples with concisely controlled atomic ratios (Cu : Pt) are prepared by a facile strategy. We demonstrate that Cu-Pt (3 : 1) NCs exhibit the highest activity and faradaic efficiency in the CO2 electroreduction reaction among all the as-prepared samples.
