CO2 electrolysis is considered a promising strategy for producing valuable chemicals. However, it is challenging to selectively convert CO2 into long-chain carbon chemicals due to the difficulty of controlling complex C─C coupling during the reaction process. In their Research Article (e202502740), Takayoshi Ishimoto, Miho Yamauchi et al. demonstrate the effective enhancement of in-situ Raman scattering signals by employing precisely designed electrode structures, which reveal that the crucial step in C─C coupling is the asymmetric coupling of CO and CH2, thereby advancing CO2 electroreduction to the production of long-chain carbon chemicals.
