Iron Nanoparticles on Porous Carbon Discs: Electrocatalysts with Over 30% Energy Efficiencies for the Production of Ammonia from Nitrate
Year: 2025
Type: article
Abstract: Disc‐shaped precursor materials (Fe‐HBD) are prepared by the complexation of iron with 2,5‐dihydroxy‐1,4‐benzoquinone. Through the carbonization of Fe‐HBD at 700 °C, Fe nanoparticles on carbon disc matrixes (CD@Fe‐700) are synthesized. The CD@Fe‐700 with a high surface area of 424 m 2 g −1 and micro/mesoporosity showed promising electrocatalytic performance in the nitrate reduction reaction (NO 3 RR) to ammonia with ammonia yield rates of 1.8–13.5 mg h −1 cm −2 at overpotentials of −0.2–−0.6 V (vs. RHE), reaching energy efficiencies up to 32.6–34.7%.
