Abstract

Iron oxide nanoparticles (FeO_x NPs, 5-30 nm size) prepared via laser ablation in liquid were supported onto Indium Tin Oxide conductive glass slides by magnetophoretic deposition (MD) technique. The resulting FeO_x@ITO electrodes are characterized by a low amount of iron coverage of 16-50 nmol/cm², and show electrocatalytic activity towards water oxidation in neutral phosphate buffer pH 7 with 0.58 V overpotential and quantitative Faradaic efficiency towards oxygen production. XPS analysis on the oxygen region of the FeO_x films reveals a substantial hydration of the surface after catalysis, recognized as a crucial step to access reactivity.
