Oxygen vacancy-engineered Fe2O3 nanocubes via a task-specific ionic liquid for electrocatalytic N2 fixation

Abstract

A task-specific ionic liquid strategy was, for the first time, proposed for designing oxygen vacancy-rich α-Fe₂O₃ nanocubes toward electrocatalytic N₂ fixation to NH₃ under ambient conditions, offering a NH₃ formation rate of 32.13 μg h⁻¹ mg_cat⁻¹ with a faradaic efficiency of 6.63% at −0.3 V vs. the reversible hydrogen electrode.
