摘要：
The faradaic efficiency of Bi2WO6 is 62.0% at -0.3 V vs. RHE, an improvement of 1.4- and 1.8-times relative to Bi2O3 and WO3 for the nitrate reduction reaction. In addition, the catalysis occurring on Bi2WO6 follows the pathway: *NO3-*NO2-*NO-*NOH-*HNOH-*H2NOH-*NH3, as verified by operando Raman spectroscopy and theoretical calculations.
