Abstract The electrochemical reduction of carbon dioxide (CO 2 RR) to high‐value chemicals offers a promising approach storing renewable energy while helping close the anthropogenic loop. use porous solid electrolytes (PSE) makes CO RR more sustainable because they are recyclable and can produce pure liquid products free electrolyte contaminants. However, current PSEs have several limitations including insufficient ion conduction poor scalability. Here, sulfonated NUS‐10 covalent organic framework (COF) foams demonstrated as for efficient capable producing valuable formic acid, monoxide, C 2+ compounds. A straightforward, scalable microwave‐assisted synthesis method is outlined COF nanosheets, which be freeze‐dried create proton exchange foams. These exhibit high conductivity (σ = 0.052 S cm −1 at 30 °C) easily recycled without mass loss across multiple device operations. When applied in PSE electrolyzers, exhibites exceptional efficiency, requiring less than 4 V cell voltage 200 mA −2 density high‐purity acid. This study advances development RR, offering path toward practical applications RR.
