FeMoO₄ nanorods for efficient ambient electrochemical nitrogen reduction

Abstract

Herein, FeMoO₄ nanorods are explored as an efficient electrocatalyst for nitrogen reduction reaction (NRR) in 0.1 M Na₂SO₄ solution, with an NH₃ yield rate of 17.51 μg h^-1 mg^-1 and a high faradaic efficiency (FE) of 10.53%. Density functional theory (DFT) calculations reveal that surface Fe atoms are the active centers for NRR via an alternating mechanism.
