    Abstract Hybrid electrodes with improved O2tolerance and capability of CO2conversion into liquid products in the presence of O2are presented. Aniline molecules are introduced into the pore structure of a polymer of intrinsic microporosity to expand its gas separation functionality beyond pure physical sieving. The chemical interaction between the acidic CO2molecule and the basic amino group of aniline renders enhanced CO2separation from O2. Loaded with a cobalt phthalocyanine‐based cathode catalyst, the hybrid electrode achieves a CO Faradaic efficiency of 71 % with 10 % O2in the CO2feed gas. The electrode can still produce CO at an O2/CO2ratio as high as 9:1. Switching to a Sn‐based catalyst, for the first time O2‐tolerant CO2electroreduction to liquid products is realized, generating formate with nearly 100 % selectivity and a current density of 56.7 mA cm−2in the presence of 5 % O2.
