Photoelectrochemical properties of Fe2O3 nanorods grown with an Na2SO4 additive

다국어 초록 (Multilingual Abstract)

Fe2O3 photoelectrodes were grown using a microwave chemical bath deposition (MW-CBD) method with an Na2SO4 additive at various concentrations. We investigated the effects of the Na2SO4 additive concentration on the morphological, optical, structural, electrical, and photoelectrochemical properties of the Fe2O3 photoelectrodes using scanning electron microscopy, ultraviolet-visible spectroscopy, X-ray diffraction, electrochemical impedance spectroscopy and potentiostat/galvanostat measurements, respectively. The Na2SO4 concentration was found to affect the properties of the Fe2O3 photoelectrodes, including the photoelectrochemical properties. Consequently, the highest photocurrent density value of 0.39 mA/cm2 was obtained from the sample prepared with an Na2SO4 concentration of 0.03 M.
