碳基催化材料在电化学还原二氧化碳中的研究进展

Converting carbon dioxide (CO₂) into high-energy fuel or high-value chemicals by electrochemical reduction technology is an effective way to enhance the added value of CO₂ utilization and alleviate the pressure of CO₂ emission, and is also one of the conversion and storage methods for green energy such as wind power, hydropower and solar energy, which is of great significance to “peak-clipping and valley-filling” of intermittent power. One of the keys to realize high-efficiency electrochemical reduction of CO₂ lies in the creation of high-performance electrocatalytic materials. In this paper, the research progress of carbon-based catalytic materials for electrochemical reduction of CO₂ is reviewed, and the structural characteristics of intrinsic defective carbon materials, doped carbon materials, carbon-based composites and monolithic carbon materials are discussed. On this basis, the challenges and future development of carbon-based catalytic materials for electrochemical reduction of CO₂ are prospected.
