International society has been making efforts to reduce greenhouse gas emission to alleviate the climate change. Since the carbon neutrality declaration by many countries in 2020, the world has established policies and strategies, and has enacted laws to achieve the carbon neutrality. The various key technologies capable of contributing to the greenhouse gas reduction target include photovoltaics, wind power, hydrogen, bioenergy, energy efficiency improvement, industrial decarbonization, and carbon capture, utilization and storage (CCUS). In particular, the CCUS technologies are considered to be the final ones to capture, convert and store the inevitably emitted CO2 from the industry. The electrochemical CO2 conversion is great attention as the promising technology to reduce CO2 electrochemically to value-added chemicals or fuels. To improve the CO2 conversion efficiency of the production of the valuable products, various obstacles including insufficient activity/selectivity of the CO2 reduction catalysts, low ionic conductivity of the ion-exchange membranes, and physicochemical/electrochemical stability of each component and the entire system. Additionally, the mechanisms of the electrochemical CO2 reduction and purverization of the catalysts are not clearly understood. Here, the recent research of electrochemical CO2 conversion will be introduced for the production CO2-derived carbon-neutral products. Additionally, formate production mechanism from CO2 on the SnOx surface with oxygen vacancy will be proposed as well.
