Abstract

Electrosynthesis of ammonia from nitrate is very promising. Herein, spatially-confined high-entropy building block-like Fe/Mn mixed phases species were integrated into porous carbon nanofibers for electrosynthesis of ammonia, affording a yield of 35.6 ± 1.1 mg h⁻¹ mg_cat⁻¹ and a faradaic efficiency of 91.8 ± 2.8% at −1.1 V vs. RHE.
