SZSong Zhang LSLing‐ling Shan JLJing-Jing Liang

Key Points

This research aims to explore the effectiveness of Fe3C/Fe nanoparticles embedded in n-doped carbon as catalysts for the nitrogen reduction reaction (NRR) to produce ammonia.
Utilized Fe3C/Fe nanoparticles embedded in n-doped carbon as catalysts.
Evaluated electrocatalytic performance in nitrogen reduction to ammonia under controlled conditions.
Measured competition against hydrogen evolution reactions.
Enhanced ammonia production observed with catalytic efficiency improvements.
Optimal conditions led to significant decreases in energy barriers for NRR.
Reduced rates of competing hydrogen evolution reactions were achieved.

Abstract

The electrocatalytic nitrogen reduction reaction (NRR) offers a sustainable route for ammonia synthesis but is severely hindered by the inertness of N₂, its low solubility, and the competing hydrogen evolution...
