Abstract
- Electrocatalytic nitrate (NO<subscript>3</subscript><superscript>−</superscript>) reduction has emerged as an attractive dual-function strategy to produce ammonia (NH<subscript>3</subscript>) and simultaneously mitigate environmental issues. However, efficient electrocatalysts with high selectivity for NH<subscript>3</subscript> synthesis are highly desired. In this work, we report the Co–NCNT nanohybrid as a highly active electrocatalyst towards NO<subscript>3</subscript><superscript>−</superscript>-to-NH<subscript>3</subscript> conversion. In 0.1 M NaOH solution containing 0.1 M NO<subscript>3</subscript><superscript>−</superscript>, the Co–NCNT catalyst is capable of attaining a large NH<subscript>3</subscript> yield of 5996 μg h<superscript>−1</superscript> cm<superscript>−2</superscript> and a high faradaic efficiency of 92% at −0.6 V versus reversible hydrogen electrode. Moreover, it displays excellent electrochemical stability. [ABSTRACT FROM AUTHOR]
