Abstract

Abstract : A bimetallic FeCo2 O4 spinel nanowire array grown on carbon cloth is highly active and stable for electrocatalytic NO3 − reduction to NH3, capable of attaining a large NH3 yield of 4988 μg h −1 cm −2 with a high faradaic efficiency of 95.9%. Abstract : 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 FeCo2 O4 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.
