Electrochemical synthesis of propylene from carbon dioxide on copper nanocrystals.

ABSTRACT: The conversion of carbon dioxide to value-added products using renewable electricity would potentially help to address current climate concerns. The electrochemical reduction of carbon dioxide to propylene, a critical feedstock, requires multiple C-C coupling steps with the transfer of 18 electrons per propylene molecule, and hence is kinetically sluggish. Here we present the electrosynthesis of propylene from carbon dioxide on copper nanocrystals with a peak geometric current density of -5.5 mA cm^-2. The metallic copper nanocrystals formed from CuCl precursor present preponderant Cu(100) and Cu(111) facets, likely to favour the adsorption of key *C₁ and *C₂ intermediates. Strikingly, the production rate of propylene drops substantially when carbon monoxide
