To surmount the shortcomings of powder-based catalysts and small electrode sizes, development meter-scale integrated materials is essential for practical electrocatalytic applications, which requires fine control over effective surface grafting catalytic active sites on large-size electrodes as well addressing challenge balancing cost-effective large-scale manufacturing with highly stable operation. Herein, we report a low-cost, facile, scalable method directly constructing single-molecule-integrated using commercially available, flexible, size-tailored conductive carbon textiles (e.g., graphite felt) well-defined planar conjugated molecules metallophthalocyanines) via heterostacking steered cross-scale heterointerfacial assembly. This universal unlocks limitations traditional approaches that involve integrating catalysts, particles, binders Nafion), supported paper) through multiple processing steps typically result in centimeter-level electrodes. Meaningfully, our enables precise size, composition, microenvironment, structure to match various environments. As proof concept, an thiophene-gilded cobalt phthalocyanine demonstrates outstanding activity stability CO2 electroconversion alkaline, neutral, acidic media under industrially relevant current densities, even flowing paired-electrolysis system. study provides comprehensive scientific data engineering guidance systematic design scalable, binder-free electrodes, thereby promising drive sustainable energy-efficient electrolysis industrial scene.
