Phosphorus-rich CoP₄@N–C nanoarrays for efficient nitrate-to-ammonia electroreduction

Abstract

The electrochemical nitrate reduction reaction (NO3−RR) is a novel green method for ammonia synthesis. However, the lack of sufficient catalysts has hindered the development of NO3−RR. This research develops a...

Electrodeposition of a 3D dendritic Cu–Sn bimetallic alloy for electrocatalytic nitrate reduction to ammonia

“…Nitrate (NO 3 − ) is a relatively ideal candidate due to the lower dissociation energy of NO (204 kJ mol −1 ) as well as its environmental pollutant properties. 19–23 The electrocatalytic NO 3 − reduction reaction (NO 3 RR) to NH 3 can not only treat environmental pollutants but also produce high value-added products, thus achieving “two birds with one stone”. The electrocatalytic NO 3 − -to-NH 3 process is an eight-electron-transfer step and can easily generate various undesired by-products; therefore, electrocatalysts with high selectivity and yield for NH 3 are urgently needed.…”
