AB  - WO3/TiO2 and TiO2 coatings were prepared on titania substrates using facile and cost-effective plasma electrolytic oxidation process. The coatings were characterized by X-ray diffraction, scanning electron microscopy, Raman, UV vis diffuse reflectance spectroscopy, and X-ray photoelectron spectroscopy. With increasing duration of PEO process, the monoclinic WO3 phase became dominant and new monoclinic WO2.95 phase appeared. The optical absorption edge in the WO3/TiO2 samples, enriched with WO3/WO2.96 phase, was shifted to the visible region. The photocatalytic efficiency of WO3/TiO2 and pure TiO2 samples was evaluated by performing the photodegradation experiments in an aqueous solution of Rhodamine 6G and Mordant Blue 9 under the visible and UV light. The WO3/TiO2 catalysts are much more efficient than pure TiO2 under visible light and slightly better under UV light. The improvement of photocatalytic activity in the visible region is attributed to better light absorption, higher adsorption affinity and increased charge separation efficiency.

AB  - TiO2/WO3 composites supported on a stainless steel foil were prepared by the spray pyrolysis technique. Content of WO3 was gradually increased from 1 wt% to 100 wt.%, while the coating thickness was limited to about 1 pm. The coatings were characterized by X-ray diffraction, scanning electron microscopy, atomic force microscopy, X-ray photoelectron spectroscopy, and Raman spectroscopy. The photocatalytic activity of obtained coatings was investigated by degradation of methyl orange, used as model pollutant. The results show that with increasing WO3 content up to 10 wt.% photoactivity increases as result of better charge separation that could effectively prevent the recombination of photogenerated electrons and holes. Further increase of WO3 content led to decrease of photoactivity. (C) 2014 Elsevier B.V. All rights reserved.
