Dopant-Induced Electronic States Regulation Boosting Electroreduction of Dilute Nitrate to Ammonium.

Electrochemically converting NO into NH offers a promising route for water treatment. Nevertheless, electroreduction of dilute NO is still suffering from low activity and/or selectivity. Herein, B as a modifier was introduced to tune electronic states of Cu and further regulate the performance of electrochemical NO reduction reaction (NO RR) with dilute NO concentration (≤100 ppm NO -N).
