Copper is a peculiar element in the electrocatalytic reduction of CO2, an area of growing relevance. Sub-nano Cu clusters have been suggested by computational studies to be good candidate for CO2 reduction, being able to lower the overpotential in the reaction. However, there is no clear evidence on how these sub-nano copper particles behave during electrocatalytic conditions. Here, we report an electrochemical investigation of two size-controlled Cu nanoclusters, prepared by a deposition method developed at the Argonne National Laboratory (ANL).The absence of organic ligands or capping agents in the resulting clusters, even at the level of contamination (which cannot be avoided in conventional wet techniques) makes these materials very interesting for electrocatalytic studies.

Abstract
Copper is a peculiar element in the electrocatalytic reduction of CO2, an area of growing relevance. Sub-nano Cu clusters have been suggested by computational studies to be good candidate for CO2 reduction, being able to lower the overpotential in the reaction. However, there is no clear evidence on how these sub-nano copper particles behave during electrocatalytic conditions. Here, we report an electrochemical investigation of two size-controlled Cu nanoclusters, prepared by a deposition method developed at the Argonne National Laboratory (ANL).The absence of organic ligands or capping agents in the resulting clusters, even at the level of contamination (which cannot be avoided in conventional wet techniques) makes these materials very interesting for electrocatalytic studies.Pubblicazioni consigliate
