Implementing carbon cycling is an urgent requirement for human society and a hot research topic in the catalysis field. With the promotion of renewable energy, electrocatalysis technology has gained widespread attention and can achieve different target products by changing the reaction voltage. Based on this, electrocatalysis technology is considered an effective strategy to alleviate the current energy crisis and environmental problems, and is of great significance for achieving carbon neutrality. Among them, electrocatalytic CO2 reduction reaction (CO2RR) is a promising small molecule conversion strategy. However, CO2 and its linear molecule have high chemical inertness due to the high dissociation energy of C=O. Due to the similar redox potentials of CO2RR and hydrogen evolution reaction (HER), there is a competitive relationship between them, which is also an important factor leading to the low conversion efficiency of catalysts in CO2RR. Therefore, CO2RR still faces problems such as high overpotential and low Faradaic efficiency. To overcome these bottlenecks and enhance the electrocatalytic performance of CO2RR, it is necessary to find a suitable CEPT entity to achieve the synergistic transfer of electrons and protons in the CO2 electrocatalytic reduction system, while maintaining the structural stability of the catalyst and the oxidation state cycle of the active component, which still requires a lot of research
