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).

Recent Advances of the Confinement Effects Boosting Electrochemical CO Reduction.

Powered by clean and renewable energy, electrocatalytic CO reduction reaction (CO RR) to chemical feedstocks is an effective way to mitigate the greenhouse effect and artificially close the carbon cycle. However, the performance of electrocatalytic CO RR was impeded by the strong thermodynamic stability of CO molecules and the high susceptibility to hydrogen evolution reaction (HER) in aqueous phase systems. Moreover, the numerous reaction intermediates formed at very near potentials lead to poor selectivity of reaction products, further preventing the industrialization of CO RR.
