Keywords: | PEO;Photocatalysis;TiO 2;TiO /Sb O 2 2 3 | Issue Date: | 15-Feb-2022 | Journal: | Materials Letters | Abstract: | Anatase TiO2 coatings modified by Sb2O3 particles were formed by plasma electrolytic oxidation of titanium in 10 g/L Na3PO4⋅10H2O with addition of Sb2O3 particles. The photodegradation of methyl orange under simulated sunlight was used to probe the photocatalytic potential of TiO2/Sb2O3 coatings. The photocatalytic activity (PA) of obtained coatings is higher than pure TiO2 for adding up to 2.0 g/L of Sb2O3 particles to electrolyte. The highest PA was observed for coatings formed in electrolyte with the addition of 0.75 g/L Sb2O3. Increased PA is related to a decrease of photogenerated electron/hole recombination rate as a result of TiO2 and Sb2O3 coupling. |
