Electrocatalytic reduction of CO2 to hydrocabons have received a great deal of attention as a promising way to facilitate a closed carbon-cycle. While most metal-based electrocatalysts produce C1 chemicals, C2 reduction species such as ethylene and ethanes only been produced in Cu-based catalysts. However, the selectivity control of C2 products from Cu electrocatalysts have not been achieved so far. In this presentation, the nanostructure effect on the selective-production of C2 chemicals will be demonstrated. By precise control of design factors of nanostructures on Cu electrodes, reaction kinetics and intermediate stability could be controlled, resulting in high C2 chemical selectivity.
