Mixed Al2O3/ZnO coatings are prepared by conventional DC plasma electrolytic oxidation (PEO) of aluminum in boric acid and borax solution containing ZnO nanoparticles. Scanning electron microscopy equipped with energy dispersive x-ray spectroscopy, x-ray diffraction, and Raman spectroscopy were employed to monitor morphological, structural, and chemical changes of obtained oxide coatings. It was found that chemical and phase compositions strongly depend on PEO time. Photoluminescence and photodegradation of methyl orange served as a tool to estimate potential application of Al2O3/ZnO coatings. Photoluminescence measurements showed that clearly observable bands inherent to Al2O3 and ZnO are present in formed coatings, pointing at oxygen vacancies as the main source of photoluminescence. Longer PEO processing times proved beneficial for enhanced photocatalytic activity.
