A FeCo2O4 nanowire array enabled electrochemical nitrate conversion to ammonia

Electrocatalytic nitrate (NO3−) reduction not only generates high-value ammonia (NH3) but holds significant potential in the control of NO3− contaminants in natural environments. Here, a bimetallic FeCo2O4 spinel nanowire array grown on carbon cloth is proposed as an efficient electrocatalyst for th...

Zusammenfassung:Electrocatalytic nitrate (NO3−) reduction not only generates high-value ammonia (NH3) but holds significant potential in the control of NO3− contaminants in natural environments. Here, a bimetallic FeCo2O4 spinel nanowire array grown on carbon cloth is proposed as an efficient electrocatalyst for the conversion of NO3− to NH3 with a high faradaic efficiency of up to 95.9% and a large NH3 yield of 4988 μg h−1 cm−2. Furthermore, it also exhibits excellent stability during 16 h electrolysis.
