Regulating the reaction zone of electrochemical CO₂ reduction on gas-diffusion electrodes by distinctive hydrophilic-hydrophobic catalyst layers

Regulating the rational wettability on gas-diffusion electrodes (GDEs) plays a pivotal role to improve the efficiency of CO₂RR via fine-tuning the reaction zone and boosting the formation of triple-phase interfaces. Herein, we present a wettability regulation strategy that modulates the triple-phase reaction zone in the catalyst...
