【Abstract】 It is one of the effective routes for the electrochemical conversion of CO₂ into high-value fuels and chemicals driven by solar and wind energy to alleviate the greenhouse effect and reduce carbon emission. Copper-based catalysts for the conversion of CO₂ to hydrocarbons have attracted great concerns. However, high reaction overpotential, poor selectivity of target products, and low stability are great challenges in the development of copper-based catalysts. In this paper, the reaction mechanisms of electrocatalytic CO₂ to ethylene were introduced. The morphology and crystal facet regulation, defect construction, heteroatomic doping, and bimetallic alloy formation and their effects on the performance of Cu-based catalysts were also summarized. This review provides a reference for the research and development of a high-efficiency catalyst for electrocatalytic CO₂ reduction to ethylene.更多还原
