Abstract Electrochemical CO 2 reduction reaction (CO RR) coupled with renewable electricity holds promises for efficient mitigation of carbon emission impacts on the environment and turning into valuable chemicals. One important task in RR development is design fabrication electrodes stable operation long term. Gas‐diffusion (GDEs) have been employed to continuously feed electrolyzers. Despite significant advances GDE tailoring properties, present GDEs often suffer from critical issue flooding due electrowetting carbon‐based substrates, which hinders transition industrial application. To address flooding, intrinsically hydrophobic polymeric substrates recently fabricated shown promising performances. Herein, challenges associated carbon‐free are reviewed RR.
