Abstract The electrochemical CO 2 reduction reaction (CO RR) to valuable C 2+ products emerges as a promising strategy for converting intermittent renewable energy into high‐energy‐density fuels and feedstock. Leveraging its substantial commercial potential compatibility with existing infrastructure, the conversion of multicarbon hydrocarbons oxygenates (C ) holds great industrial promise. However, process is hampered by complex multielectron‐proton transfer reactions difficulties in reactant activation, posing significant thermodynamic kinetic barriers commercialization production. Addressing these necessitates comprehensive approach encompassing multiple facets, including effective control C─C coupling electrolyzers using efficient catalysts optimized local environments. This review delves advancements outstanding challenges spanning from microcosmic macroscopic scales, design nanocatalysts, optimization microenvironment, development electrolyzers. By elucidating influence electrolyte environment, exploring flow cells, guidelines are provided future research aimed at promoting coupling, thereby bridging microscopic insights applications field electroreduction.
