Special Issue Information

Dear Colleagues,

Anodized minerals are obtained on the “valve metals” and their alloy surface through relatively easy electrochemical processes. The nanostructured materials produced during these procedures are characterized by unique morphology, chemical composition, and structure, which can be controlled by changing the conditions and parameters of fabrication processes. Depending of the substrate materials, anodization type, and process conditions, it is possible to obtain many forms of anodized materials, i.e., from nanopores and nanotubes on aluminium or titanium, through nanorods on copper, to sponge on zinc. However, many scientific publications on anodized materials focus only on the influence of process conditions on their morphology/structure, whereas research on the potential application of these materials is negligible. A wide range of obtainable morphologies/structures ensures that anodized materials are successfully used in wide applications in such scientific fields as optics, biotechnology, supercapacitors, LEDs, catalysis, photocatalysis, sensing, electronic devices, electrochemistry, plasmonics, surface-enhanced Raman spectroscopy, and others. Moreover, the change of structure and/or morphology determines the interesting properties and possibilities of using anodized materials, and this is the essence of materials science.

This Special Issue will be focused on the top trends in the wide range of applications of various anodized materials. The aim of this Special Issue will be to provide the current state-of-the-art on the application of various anodized materials in different scientific fields. Reports on the unique properties of anodized materials and their expected applications are also welcome. It is my pleasure to invite all authors with expertise in the abovementioned topics to submit their manuscripts to Materials. All noteworthy and highly original research papers, communications, and review articles covering the current state-of-the-art are welcome.

My wish is for this collection to contribute to the development of new ideas for the research and applications of anodized minerals.

Nanoporous tin oxide layers obtained via anodic oxidation of metallic tin at the potential of 4 V in the alkaline electrolyte (1 M NaOH) were soaked in distilled water for various durations (from 2 h to 120 h) to verify the influence of water-enabled crystallization on the morphology, composition, and related optical and photoelectrochemical properties of such kind of anodic SnOx. Although water soaking generally contributes to more stoichiometric and crystalline tin oxide, it was confirmed that at the initial stages of the water-induced dissolution–redeposition process, material exhibits enhanced photoelectrochemical performance under simulated sunlight irradiation. However, long-time exposure to water results in a gradual widening of the material’s band gap, shifting of the photoelectrochemical spectra towards higher energies, and almost complete deterioration of the photoelectrochemical activity under sunlight irradiation.

The anodization of commercially pure Ti alloy (99.5 wt %) and two biomedical titanium alloys, Ti6Al7Nb and Ti6Al4V, was performed, and the resulting anodic oxides were studied. The biomedical alloys were made by Laser Engineered Net Shaping. The glycol-based and glycerol-based electrolytes with 0.3 M ammonium fluoride and 2 wt % of deionized water content were tested. It was found that electrolyte type as well as the chemical composition of the base substrate affected the final morphology and chemical composition of the anodic oxide formed. A higher current density, ionic mobility, and oxide growth rate were obtained in glycol-based electrolyte as compared to those obtained in glycerol-based electrolyte for all tested alloys. A self-organized nanotubular and nanoporous morphology of the anodic oxide in both types of electrolyte was obtained. In each electrolyte, the alloy susceptibility to oxidation increased in the following order: Ti6Al4V < Ti 99.5% < Ti6Al7Nb, which can be correlated to the oxidation susceptibility of the base titanium alloy. It was observed that the more impurities/alloying elements in the substrate, the lower the pore diameters of anodic oxide. There was a higher observed incorporation of electrolyte species into the anodic oxide matrix in the glycerol-based electrolyte compared with that in glycol-based electrolyte. Full article
