Unlocking Synergistic Electrothermal Catalysis on Defective Carbon for On-Demand Ammonia Production
Abstract
Closing the anthropogenic nitrogen loop demands innovative technologies that can simultaneously remediate nitrate pollution and produce valuable ammonia (NH 3 ) in a decentralized and sustainable manner. Herein, we establish a metal-free catalytic framework for the nitrate reduction reaction (NO 3 RR) by synergistically integrating vacancy-defect engineering with a mild electrothermal coupling strategy (90% reduction in carbon footprint relative to conventional industrial routes. The significance of this work lies in the conceptual integration of defect engineering and electrothermal operation within a metal-free NO 3 RR system, offering a generalizable strategy for low-carbon nitrate remediation and nitrogen valorization.
