Gas sensing properties of the nanostructured anodic Zr–W oxide film

On the Growth of Thin Anodic Oxides Showing Interference Colors on Valve Metals

“…ZrO 2 coatings are commonly employed to further reduce corrosion rate, and especially in the production of biomedical implants the ASD process can be applied to produce crystalline films with tunable composition [14]. On the other hand, its oxide exhibits peculiar functional properties, including high dielectric constant, luminescence and the possibility to obtain ionic conductivity -and related gas-sensing ability and suitability as solid electrolyte: therefore, ZrO 2 films gained interest in the production of optical and electronic devices [49][50][51][52][53]. Common electrolytes used in zirconium anodizing process are sulfate-based ones (H 2 SO 4 , Na 2 SO 4 , K 2 SO 4 ), borate based ones (ammonium borate), carbonate based ones, caustic solutions (NaOH, KOH).…”

Nanotubular ZrTiO4 Prepared on Sputter Deposited Zr−Ti Films by Anodization

“…[6] Sputtered ZrÀ Al, ZrÀ W, and ZrÀ Ti alloy on Si substrates were used for preparing nanotube oxide films due to the superior dielectric properties of mixed oxides. [7] Oxygen vacancies can be induced by anodizing mixed alloy and further stabilized tetragonal-ZrO 2 , which is responsible for the good dielectric property. Besides, ZrTiO 4 is also suitable for microwave devices and photocatalytic due to its high dielectric constant, low dielectric losses and new catalytic sites.…”

Formation of layered structure porous‐type anodic alumina films locally with a solution flow‐type micro‐droplet cell

“…Zheng et al reported the formation of hydrophobic oxide films on aluminum by anodizing in phosphoric acid solution followed by desiccation and that a high contact angle surface formed on aluminum samples showed superior corrosion resistance. Vázquez et al reported on the gas‐sensing properties of nanostructured anodized Zr‐W oxide films using porous‐type anodic alumina layers …”
