Electrochemical carbon dioxide reduction reaction(CO_(2)RR)provides a promising way to convert CO_(2)to chemicals.The multicarbon(C_(2+))products,especially ethylene,are of great interest due to their versatile industrial applications.However,selectively reducing CO_(2)to ethylene is still challenging as the additional energy required for the C–C coupling step results in large overpotential and many competing products.Nonetheless,mechanistic understanding of the key steps and preferred reaction pathways/conditions,as well as rational design of novel catalysts for ethylene production have been regarded as promising approaches to achieving the highly efficient and selective CO_(2)RR.In this review,we first illustrate the key steps for CO_(2)RR to ethylene(e.g.,CO_(2)adsorption/activation,formation of~*CO intermediate,C–C coupling step),offering mechanistic understanding of CO_(2)RR conversion to ethylene.Then the alternative reaction pathways and conditions for the formation of ethylene and competitive products(C_1 and other C_(2+)products)are investigated,guiding the further design and development of preferred conditions for ethylene generation.Engineering strategies of Cu-based catalysts for CO_(2)RR-ethylene are further summarized,and the correlations of reaction mechanism/pathways,engineering strategies and selectivity are elaborated.Finally,major challenges and perspectives in the research area of CO_(2)RR are proposed for future development and practical applications.

Electrochemical carbon dioxide reduction(ECR)is an attractive pathway to synthesize useful fuels and chemical feedstocks,especially when paired with renewable electricity as the energy source.In this overview,we examine the recently witnessed advances and on-going pursuits of ECR in terms of the key fundamental mechanisms,basic experimentation principles,electrocatalysts and the electrochemical setup for ECR,aiming at offering timely key insights into solving the unsettled bottleneck issues.The reaction pathways are discussed in relation to the generation of single-,double-and multi-carbon products by the ECR,as well as the underlying principles in catalyst design to form them both efficiently and selectively.For the rational design of electrocatalysis,we look into the critically important roles played by various in situ and operando experimental techniques and computational simulations,where the key priorities are to engineer the highly active and selec-tive ECR catalysts for the specifically targeted products.Indeed,with the purposely designed high activity and selectivity,one would be able to“magically”transform a bottle of CO_(2)-riched“coke drink”to a glass of“beer”with the desired alcohol product in a layman term,instead of a bottle of formic acid.Nonetheless,there are still considerable complications and challenges ahead.As a dynamically rapid-advancing research frontier for both energy and the environment,there are great opportunities and obstacles in the ECR scale up.
