TiO2 coatings modified by Bi2O3 particles were successfully formed by plasma electrolytic oxidation (PEO) process of titanium in supporting electrolyte (10 g/L Na3PO4·10H2O) with the addition of Bi2O3 particles. The morphology, crystal structure, chemical composition, and optical properties of formed PEO coatings were investigated by scanning electron microscopy, energy-dispersive spectroscopy, X-ray fluorescence, X-ray diffraction, X-ray photoelectron spectroscopy, UV–Vis diffuse reflectance spectroscopy, and photoluminescent techniques. The photodegradation of methyl orange under simulated sunlight condition was used to determine the potential of TiO2/Bi2O3 coatings in photocatalysis. The photocatalytic activity (PA) of TiO2/Bi2O3 coatings is higher than that of pure TiO2. PA of TiO2/Bi2O3 coatings is highly dependent on the amount of Bi2O3 particles in the supporting electrolyte and the highest PA was observed for TiO2/Bi2O3 coating formed in supporting electrolyte with the addition... of 1.2 g/L of Bi2O3 particles. Enhanced PA is related to the reduction of photo-generated electron/hole recombination rate as a result of TiO2 and Bi2O3 coupling.
