Abstract
Electroreduction of nitrite to ammonia (NO2RR) is recognized as an appealing method for achieving renewable NH3 production and waste NO2− removal. Herein, monodispersed W-doped ZnO (W1-ZnO) is developed as an efficient NO2RR catalyst. Theoretical simulations and in situ spectroscopic measurements unravel that the enhanced NO2RR property of W1-ZnO originates from the creation of active W1-Zn dinuclear sites to selectively activate NO2− and enhance the protonation energetics of NO2−-to-NH3 pathway, whilst repelling the competing H2 evolution. Strikingly, W1-ZnO equipped in flow cell shows an impressive NO2RR performance with NH3 yield rate of 970 μmol h−1 cm−2 and NH3-Faradaic efficiency of 94.5%.
