Peroxide‐Driven Nitrogen Fixation Reactions for Energy Storage Applications

Advanced Energy Materials, EarlyView.
Sustainable ammonia synthesis from air as a hydrogen energy carrier and storage medium is demonstrated via an efficient dual‐step electrochemical approach at ultralow overpotential (−0.1 V vs. RHE). Atmospheric nitrogen is first oxidized to nitrate using in situ generated peroxide, then directly converts to ammonia on the same electrode, achieving ...
