Abstract

Electrocatalytic nitrate (NO) reduction not only generates high-value ammonia (NH) but holds significant potential in the control of NO contaminants in natural environments. Here, a bimetallic FeCoO spinel nanowire array grown on carbon cloth is proposed as an efficient electrocatalyst for the conversion of NO to NH with a high faradaic efficiency of up to 95.9% and a large NH yield of 4988 μg h cm. Furthermore, it also exhibits excellent stability during 16 h electrolysis.

摘要

电催化硝酸盐（NO）还原不仅能生成高价值的氨（NH₃），而且在控制自然环境中的NO污染物方面具有巨大潜力。在此，提出一种生长在碳布上的双金属FeCoO尖晶石纳米线阵列作为一种高效的电催化剂，用于将NO转化为NH₃，其法拉第效率高达95.9%，NH₃产率高达4988 μg h⁻¹ cm⁻²。此外，在16小时的电解过程中，它还表现出优异的稳定性。
