Abstract

A green route of electrochemical ammonia synthesis was realized for the first time by using doped LaFeO3 perovskite as an electrocatalyst under mild conditions. The NH3 formation rate of 13.46 μgNH3 h-1 mgcat-1 (3.52 × 10-10 mol s-1 cm-2) was achieved with the cell voltage of 2.4 V, and a faradaic efficiency of 1.99% was obtained when a cell voltage of 1.8 V was applied. The electrochemical ammonia synthesis was based on the chemisorption of N2 molecules on oxygen vacancies in perovskites and the subsequent electrochemical hydrogenation.
