Abstract
A hybrid catalyst of crystalline Fe2O3 with amorphous FeS was designed by a deep eutectic solvent approach with a subsequent annealing process, offering a high-efficiency electrocatalyst for N2 fixation with an NH3 yield of 34.31 μg h-1 mgcat.-1 and faradaic efficiency of 18.06% at -0.25 V versus a reversible hydrogen electrode.
