2D Multivariate‐Metal‐Organic Frameworks (2D‐M2OF) for High Yield Ammonia Synthesis from Nitrate
Source abstract
Abstract
Abstract Ammonia synthesis from nitrate offers a promising approach for both nitrate removal and nitrogen recycling. In this study, a series of 2D multivariate‐metal‐organic frameworks (M2OFs) is synthesized, incorporating transition metals such as Co, Ni, Mn, and Ag to enhance these processes. These M2OFs exhibit remarkable ammonia production performance, with the highest performance achieved using the quaternary structure exceeding a current density of 1 A cm−2 at −0.8 V vs RHE, with an ammonia Faradic efficiency (F.E.) of ≈90%, and a yield rate of 68 mg h−1cm−2. Our findings reveal that the synergy among different metal centers in M2OFs provides a new efficient reaction pathway for nitrate reduction via surface hydrogen co‐adsorption, a mechanism not attainable with single‐metal MOFs.
