Electrochemical carbon dioxide reduction reaction (CO2RR) provides a promising way to convert CO2 chemicals. The multicarbon (C2+) products, especially ethylene, are of great interest due their versatile industrial applications. However, selectively reducing ethylene is still challenging as the additional energy required for C-C coupling step results in large overpotential and many competing products. Nonetheless, mechanistic understanding key steps preferred pathways/conditions, well rational design novel catalysts production have been regarded approaches achieving highly efficient selective CO2RR. In this review, we first illustrate CO2RR (e.g., adsorption/activation, formation *CO intermediate, step), offering conversion ethylene. Then alternative pathways conditions competitive products (C1 other C2+ products) investigated, guiding further development generation. Engineering strategies Cu-based CO2RR-ethylene summarized, correlations mechanism/pathways, engineering selectivity elaborated. Finally, major challenges perspectives research area proposed future practical
