Abstract
ABSTRACT The electrocatalytic nitrate reduction (NO 3 RR) for rapid nitrate removal offers a sustainable wastewater treatment pathway, but suffers from low activity for practical applications. Herein, we synthesize a tandem catalyst with silver (Ag) nanoparticles implanted in iron phosphide (FeP) nanosheets, demonstrating a remarkable nitrate removal rate of 16.67 mg N L −1 h −1 (98% NO 3 − ‐N conversion and 99% N 2 selectivity via a coupled electro‐chemical pathway) and up to 40 cycles of electrocatalytic stability (6 h per cycle). Mechanistic study by a series of in situ experiments reveals a decoupling and tandem catalytic mechanism for achieving high‐rate activity: the favorable nitrate reduction to…
