摘要

Iron oxide nanoparticles (FeOx 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 FeOx@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 Voverpotential and quantitative Faradaic efficiency towards oxygen production.XPS analysis on the oxygen region of the FeOx films reveals a substantial hydration of the surface after catalysis,recognized as a crucial step to access reactivity.
