Carbon dioxide utilization is a technique that can be used to mitigate the current climate crisis by capturing industrially generated carbon dioxide from the atmosphere and converting it to useful chemicals. Research on carbon dioxide utilization has prompted scientists to explore the topic of carbon dioxide reduction through electrolysis, a technique used to generate and convert carbon dioxide to multi-carbon complexes through electrical currents. This review explores the special properties of various designs of copper electrocatalysts used in the formation of multi-carbon complexes.
