Abstract Electrocatalytic CO2 reduction (CO2RR) is an effective measure to alleviate the greenhouse effect. However, the reaction kinetics is slow and is accompanied by hydrogen evolution. Therefore, the development of catalysts with high performance has become a research hotspot of electrocatalytic CO2RR. Electrospun carbon nanofibers have been widely used in the development of electrocatalytic CO2RR catalysts due to their large specific surface area, high conductivity and controllable structure. Based on the mechanism of electrocatalysis of CO2RR, the reaction paths of formic acid, carbon monoxide, ethylene, ethanol and other products were discussed. The research progress of non-metal doped carbon nanofiber and carbon nanofiber loaded metal catalysts for electrocatalysis of CO2RR was summarized. Non-metallic doping can effectively change the surface defect density, electronic structure and surface chemical properties of the catalyst, and improve the performance of electrocatalytic CO2RR. The d-orbital level of the metal atom is close to the Fermi level, which makes it easy to accept electrons in the reaction process, to optimize the electronic structure of the catalyst, change the kinetics of the electrocatalytic CO2RR reaction, and improve the reaction rate. On this basis, the opportunities and challenges of electrocatalytic CO2 reduction catalysts for electrospinning carbon nanofibers were put forward.
