摘要: Titania films with different textural properties have been synthesized using the sol–gel spin-coating process. sols were prepared and without non ionic template agents, Pluronic P123 Brij56, in order to evaluate effect of surface developed by on their photocatalytic activity. The morphology, composition, open porosity pore size distribution these investigated transmission electronic microscopy, X-ray photoelectron spectroscopy atmospheric ellipsometric porosimetry. optical titania evaluated UV–vis transmittance spectroscopy. released after burning at 400 °C reduces refractive index coatings visible range becomes equal for naked coated soda lime glasses. In parallel, activity porous was following photodegradation kinetics Rhodamine 6G dye. Results show that increase available active affects However, this feature not only parameter responsible improvement efficiency. aggregation form dye also related film texture. This proved a marked impact performances.
