The　massive　production　of　cost-effective　and　highly-efficient　electrode　materials　is　crucial　for　industrial　CO2　electroconversion.　Herein,　this　work　breaks　away　from　conventional　approaches　by　directly　constructing　an　integrated　single-molecule　catalytic　electrode　(7F-CoPc@GF)　at　the　meter　scale,　through　the　integration　of　pi-extended　macrocyclic　structures　into　commercial　carbon-based　collectors　with　strong　interfacial　interactions.　This　innovative　method　reshapes　traditional　electrode　design　by　using　a　liquid-phase　self-adaptive　anchoring　strategy,　eliminating　the　need　for　conductive　adducts　and　binders.　In　addition,　through　introducing　the　perfluoroalkyl　chain,　the　built-in　hydrophobic　microenvironment　in　the　heterogenized　macrocycles　optimizes　the　electron　migration　and　interfacial　water　interaction　around　active　sites,　suppressing　the　hydrogen　evolution　reaction　and　thereby　enhancing　the　pH-universal　CO2　electroreduction　reaction　across　a　broad　potential　range.　Significantly,　the　mechanistic　study　reveals　that　the　hydrophobic　interfacial　microenvironment　not　only　enhances　effective　collisions　between　active　sites　and　reactants　but　also　facilitates　the　immediate　removal　of　products　from　the　electrode　surface.　Further　development　of　dual　value-added　electrolysis　systems,　incorporating　industrial　waste　gas　treatment,　highlights　the　versatility　and　extensibility　of　this　meter-scale　integrated　catalytic　electrode　material.　These　findings　offer　a　promising　methodology　for　rational　design　of　stable,　binder-free,　large-size　electrodes,　advancing　sustainable　CO2　electrolysis　at　scale.
