“…Several chemical and electrochemical methods are reported in the literature for the fabrication of ferric oxide-based electrodes [3][4][5][6][7][8][9][10][11]. Among these methods, the possibility to prepare Fe 2 O 3 by anodizing iron metal in a fluoride containing solution has been suggested in refs.…”

“…In ref. [10,11], the details on the growth mechanism of porous iron oxide layers in a fluoride containing ethylene glycol solution are deeply discussed based on the experimental evidences arising from structural and morphological characterization. According to the authors, it is easily possible to control film thickness and porosity by a careful choice of the anodizing parameter, i.e., anodizing voltage, time, and electrolyte composition.…”

Iron oxide films with a nanoporous structure were grown by anodizing sputter-deposited Fe in a fluoride containing ethylene glycol solution and annealed under air exposure at different temperatures. X-ray diffraction and Raman spectroscopy allowed to identify the presence of hematite and/or magnetite after thermal treatment for films annealed at T≥400°C under air exposure. According to GDOES compositional depth profiles, the thermal treatment sensitively reduced the amount of fluoride species incorporated into the film during the anodizing process. A band gap value of~2.0 eV was estimated for all the investigated layers, while a flat band potential dependent on both the growth conditions as well as on the annealing temperature was estimated.

“…Recently, fluoride-containing organic electrolytes have been utilized to form self-organized nanotubular and nanoporous anodic films on titanium [18,19], zirconium [20,21], niobium [22], tantalum [23] iron [24][25][26] and stainless steel [27]. The use of organic electrolytes enables the formation of thick porous anodic films on iron and stainless steel, and improves the uniformity of the self-ordered pore or nanotubular array as well as the thickening of the anodic films on valve metals.…”

Self-organised nanoporous anodic films were fabricated on 904L superaustenitic stainless steel by the electrochemical treatment in ethylene glycol electrolyte containing perchloric acid. The effects of experimental conditions, such as electrolyte temperature and applied voltage on nanoporous morphology, were studied by the way of scanning electron microscopy. The results show that lower solution temperature promotes formation of orderly nanopores. Nanoporous anodic films cannot be formed, and pitting will appear on the stainless steel when temperature is above 40uC. The sizes of pores gradually increase with increasing applied voltage when the applied voltage is lower than 30 V. Porous morphology will change from roughly circular to polygonal, and the size will change from uniform to uneven when the applied voltage is higher than 30 V. It is difficult to form orderly nanoporous anodic films when the applied voltage is too high. Difference of element content in stainless steel is also an important factor for the porous morphology. When the applied voltage is 50 V, orderly pores are formed on 316 austenitic stainless steel surface. However, under the same conditions, this phenomenon does not occur on 904L superaustenitic stainless steel surface. From the analysis of X-ray photoelectron spectroscopy, the films are composed of various metal oxides.
