The electrochemical reduction of CO2 into multi-carbon product is interesting yet requires further research. Here, the authors develop a surface strategy to achieve high CO2-to-ethylene selectivity by dodecanethiol modification CuO electrode and show that dodecanethiol facilitates CO2 transfer, enhances *CO coverage and stabilize Cu(100) facet.
