The catalytic performance of different copper surfaces towards CO2 electro-reduction was studied, the selectivity is strongly dependent on the copper morphology. It was obtained a higher selectivity towards hydrocarbons in the presence of steps and kinks, which according to DFT calculation are the active sites for this reaction.
