In the field of electrochemical CO2 reduction (CO2R), electrode engineering plays a crucial role in modulating distribution complex products. Here, based on multiphysics modeling, we demonstrate that CO2R product selectivity varies spatially along thickness catalyst layer gas diffusion (GDE). Our calculations indicate maintaining moderately low local concentration around catalytic sites enables optimal ethanol Faradaic efficiency Cu. We further developed an optimized using commercial Cu nanoparticles with loading 0.1 mg cm–2. Even under feed 30%, achieved approximately 65% for at industrial-scale current density of–156 mA cm–2 and over 80% C2+ products, promising cathodic energy more than 37% ethanol. This study serves as scalable instructive guide tuning to achieve production single high-selectivity product.
