If it is possible to synthesize C3 or higher compounds from CO₂ in electrochemical CO₂ reduction, CO₂ can be substituted for the synthesis of C3 or higher compounds even when resources are depleted, thereby realizing a society that does not need petroleum. Therefore, we investigated the formation of C3 compounds at conductive a-C electrodes with nitrogen-containing and oxygen-containing functional groups as adsorption sites and the CO₂ reduction mechanism by the role of the functional groups. The results showed that lactic acid was obtained as the main product, and the oxygen-containing and nitrogen-containing functional groups were considered to be involved.
