Copper is the catalyst widely used to produce multicarbon products for carbon dioxide reduction reaction (CO2RR). The surrounding microenvironment of copper plays a crucial role in determining its catalytic activity and selectivity. In this study, we compare three electrocatalysts with different microenvironments: pure metallic copper, metal–organic framework (MOF), MOF-derived copper–carbon composite. Operando X-ray absorption spectroscopy, transmission electron microscopy, Raman spectroscopy reveal that composite remains state, encapsulated by matrix. achieves Faradaic efficiency 75.6% C2 products, including ethylene ethanol, at current density 500 mA cm–2, 377.9 cm–2. This performance suppresses which reaches an optimal 64.5% 300 193.5 also significantly overperforms copper-MOF catalyst, shows 52.0% 400 208.0 These findings highlight importance near active sites CO2RR efficiency. We hope our results provide valuable insights advancing design reduction, contributing reduced emissions improved environmental sustainability.

Abstract Electrochemical CO 2 reduction reaction (eCO RR) has been explored extensively for mitigation of noxious gas generating C 1 and 2+ hydrocarbons oxygenates as value‐added fuels chemicals with remarkable selectivity. The source being a pure feed, it does not fully satisfy the real‐time digestion industrial exhausts. Besides detrimental effect mixture leading to global warming, there is huge capital investment in purifying flue mixtures from industries. presence other impurity gases affects eCO RR mechanism its activity selectivity toward products dwindle drastically. Impurities like NO x , SO O N halide ions present reduce conversion significantly. Instead wiping out these impurities via separation processes, new strategies material chemistry electrochemistry can open avenues turning foes friends! In this perspective, co‐electroreduction will vividly discussed supporting role different heteroatom‐containing highly stable C─N, C─S, C─X bonds, highlight existing limitations providing probable solutions attaining further success field translating exhaust streams.
