Abstract

We report the synthesis of nanostructured Fe₃S₄ from deep eutectic solvents via a one-step solvothermal method. The as-obtained Fe₃S₄ catalyst was capable of electrochemically reducing N₂ to NH₃ under ambient conditions, and exhibits a high NH₃ yield (75.4 μg h⁻¹ mg⁻¹_cat.) and faradaic efficiency (6.45%) at −0.4 V vs. a reversible hydrogen electrode.
