Published: March 21, 2025

Abstract The massive production of cost‐effective and highly‐efficient electrode materials is crucial for industrial CO 2 electroconversion. Herein, this work breaks away from conventional approaches by directly constructing an integrated single‐molecule catalytic (7F‐CoPc@GF) at the meter scale, through integration π‐extended macrocyclic structures into commercial carbon‐based collectors with strong interfacial interactions. This innovative method reshapes traditional design using a liquid‐phase self‐adaptive anchoring strategy, eliminating need conductive adducts binders. In addition, introducing perfluoroalkyl chain, built‐in hydrophobic microenvironment in heterogenized macrocycles optimizes electron migration water interaction around active sites, suppressing hydrogen evolution reaction thereby enhancing pH‐universal electroreduction across broad potential range. Significantly, mechanistic study reveals that not only enhances effective collisions between sites reactants but also facilitates immediate removal products surface. Further development dual value‐added electrolysis systems, incorporating waste gas treatment, highlights versatility extensibility meter‐scale material. These findings offer promising methodology rational stable, binder‐free, large‐size electrodes, advancing sustainable scale.
