摘要：

Nitrate (NO(3)(‒)) pollution poses significant threats to water quality and global nitrogen cycles. Alkaline electrocatalytic NO(3)(‒) reduction reaction (NO(3)RR) emerges as an attractive route for enabling NO(3)(‒) removal and sustainable ammonia (NH(3)) synthesis. However, it suffers from insufficient proton (H(+)) supply in high pH conditions, restricting NO(3)(‒)-to-NH(3) activity. Herein, we propose a halogen-mediated H(+) feeding strategy to enhance the alkaline NO(3)RR performance. Our platform achieves near-100% NH(3) Faradaic effi...
