Development of research on the conversion of carbon dioxide into fuel and high value-added products

Carbon dioxide(CO2) can be converted into clean fuel and high value-added products by CO2 capture and conversion technology, which is one of the effective ways to alleviate energy problems in the future. According to the mechanism of CO2 conversion, combined with the development of CO2 conversion technology in recent years, the research progress of the preparation of a series of high value-added products, such as methanol, formic acid, ethanol and acetic acid, by catalytic conversion technology, electrochemical reduction technology, photochemical conversion technology, photoelectric catalytic conversion technology and biological conversion technology were mainly introduced. Based on the existing technology, the CO2 conversion technology would be further developed in combination with many fields such as development of new catalysts, and cultivation and optimization of microorganisms with the function of CO2 conversion, which could play a solid foundation for large-scale industrial production and practical application of CO2 conversion technology.
