Electrosynthesis of NH₃ from low-concentration NO on cascade dual-site catalysts in neutral media.

ABSTRACT: Electrosynthesis of NH₃ from low-concentration NO (NORR) in neutral media offers a sustainable nitrogen fixation strategy but is hindered by weak NO adsorption, slow water dissociation, and sluggish hydrogenation kinetics. Herein, we propose an intriguing strategy that successfully overcomes these limitations through using an electron-donating motif to modulate NO-affinitive catalysts, thereby creating dual active site with synergistic functionality. Specifically, we integrate electron-donating nanoparticles into a Fe single-atom catalyst (Fe_SAC), where Fe sites ensure strong NO adsorption, while electron-donating motifs promote water dissociation and NO hydrogenation.
