Abstract: With the acceleration of industrialization and the development of the global economy, CO2 emissions continue to increase, leading to higher greenhouse gas concentrations and a growing climate change problem. In order to accomplish the requirements of carbon emission targets under the dual-carbon goal, the conversion of CO2 into valuable chemicals is of great significance in achieving the carbon cycle. And CO2 electrochemical reduction for the preparation of chemical fuels is one of the most promising methods for the preparation of chemical fuels with the advantages of easy operation and green color. In recent years, CO2 electrochemical reduction reaction (CO2RR) has a broad prospect for green energy conversion and storage. CO2RR is a technology that applies electrochemical methods to the electrochemical reduction of CO2 capture. In the CO2RR process, the design of the electrolytic cell is crucial because it directly affects the efficiency, selectivity and stability of the reaction. In this paper, three types of electrolytic cells commonly used for CO2RR were firstly introduced, and the advantages and disadvantages of different types of CO2 electrolytic cells were discussed, followed by analyzing the main factors affecting CO2RR in terms of both catalysts and electrolytes. Finally, a new alternative to the traditional amine-based CO2 capture method and the current research status were introduced, and the future research direction and application prospect of CO2RR process were proposed.
