Abstract
Electrocatalytic nitrate (NO
) reduction has emerged as an attractive dual-function strategy to produce ammonia (NH
) and simultaneously mitigate environmental issues. However, efficient electrocatalysts with high selectivity for NH
synthesis are highly desired. In this work, we report the Co-NCNT nanohybrid as a highly active electrocatalyst towards NO
-to-NH
conversion. In 0.1 M NaOH solution containing 0.1 M NO
, the Co-NCNT catalyst is capable of attaining a large NH
yield of 5996 μg h
cm
and a high faradaic efficiency of 92% at -0.6 V
reversible hydrogen electrode. Moreover, it displays excellent electrochemical stability.
