Research Progress in Electrochemical Technology for Reducing Carbon Dioxide

With the elevated carbon dioxide (CO2) emissions and the need for green and sustainable development, the need for electrochemical CO2 reduction technology is becoming more and more urgent. However, the electrochemical reduction technology still has difficulties and has not yet met the high requirements for large-scale industrialized production. In this paper, the field of electrochemical reduction of carbon dioxide is deeply explored from the perspectives of technological features and applications, and the progress in this field is discussed in terms of cathode materials, anode materials, and electrolytes, and the application of electrochemical technology in the field of carbon dioxide reduction is investigated concerning the differences in the generating material and loading voltage. Electrochemical carbon dioxide reduction technology can reduce carbon dioxide into utilizable industrial products by loading load voltage, and can selectively generate products such as formic acid, methanol, and methane by choosing different electrode materials and electrolytes, the selection of electrode materials and electrolytes and the selection of suitable load voltage are also the technical difficulties and the key points to realize industrial production. The electrochemical reduction of carbon dioxide technology has a wide range of applications in industrial production and energy saving and emission reduction, and this paper provides ideas for the understanding and further development of electrochemical reduction of carbon dioxide technolog.
