N2 - A disordered aluminum oxide grown on recycled aluminum sheets was synthesized by a corrosion/oxidation process. First, aluminum sheets recovered from unusable beverage cans were mechanically polished and dried in air atmosphere. Second, corrosion and oxidation into the aqueous solutions were the synthesis stages to produce aluminum oxide. Phase formation and electrical conduction of aluminum-oxide layers were validated by X-ray diffraction analysis and current–voltage plots at room temperature. An aluminum oxide-based structure operating under unusual principles at an extended lifetime resulted when an aluminum-oxide layer was inserted between two aluminum electrodes. This was attributed to an unusual electrical conduction. Some suggested models from the circuit theoretic properties are discussed here for potential usefulness for the aluminum oxide synthesized, as an environmental-friendly material that can be further useful into a sustainable scenario.
