CO₂ has attracted widespread attention because of the environmental deterioration problem from its excessive emissions. The electrochemical reduction of CO₂ to multi-carbon products is a promising option for tackling carbon emissions and restoring renewable electricity. Optimizing the morphology and enhancing the oxygen vacancy of Cu₂O has proven to be an effective strategy for boosting conversion of CO₂ to C₂ products. Here, we used a halogen-containing ionic liquid, 1-octyl-3-methylimidazolium chloride, to tailor the morphology of Cu₂O nanoparticles and increase its amount of oxygen vacancies, which exhibited excellent performance for the electrochemical reduction of CO₂ to multi-carbon products.
