Abstract
Metal corrosion, conventionally perceived as a destructive phenomenon driven by de-electronation, imposes significant economic burdens and safety hazards. To repurpose corrosion into a valuable resource, we demonstrate a macroscopic corrosion battery concept that harnesses galvanic corrosion to drive the synthesis of high-value chemicals and energy generation, challenging conventional corrosion mitigation paradigms. By spatially segregating corrosion process, the system couples anodic metal de-electronation with metal-organic frameworks (MOFs) deposition, while integrating diverse cathodic reactions including hydrogen evolution reaction, oxygen reduction, electrocatalytic hydrogenation, and hydrogen peroxide reduction with remarkable accelerated kinetics. The prototype system demonstrates concurrent production of p-aminophenol (14.3 mg cm-2 h-1) and zinc oxalate (86.9 mg cm-2 h-1) while generating 34.2 mW cm-2 of electrical power. Techno-economic analysis establishes the inaugural empirical validation of economic feasibility for corrosion-driven energy-matter symbiosis, highlighting its high gross profit. Transcending conventional corrosion engineering boundaries for inorganic synthesis, this methodology mechanistically deciphers MOF growth kinetics and advanced system design. By broadening the scope of corrosion utilization, this work enables a paradigm shift from damage mitigation to value creation, providing a blueprint for sustainable chemical-energy ecosystems.
