Mesoporous MgTa2O6 thin films with enhanced photocatalytic activity: On the interplay between crystallinity and mesostructure
Ordered mesoporous, crystalline MgTa(2)O(6) thin films with a mesoscopic nanoarchitecture were synthesized by evaporation-induced self-assembly (EISA) in combination with a sol-gel procedure. Utilization of novel templates, namely the block copolymers KLE (poly(ethylene-co-butylene)-b-poly(ethylene oxide)) and PIB6000 (CH(3)C(CH(3))(2)(CH(2)C(CH(3))(2))(107)CH(2)C(CH(3))(2)C(6)H(4)O(CH(2)CH(2)O...
متن کاملCharacterization and mesostructure control of mesoporous fluorinated organosilicate films
Mesoporous fluorinated organosilicate films were synthesized from tetramethoxysilane and perfluoroalkylsilanes (RO)3Si-R’ [R ~ Me, Et; R’ ~ (CH2)2CF3, (CH2)2(CF2)5CF3, or (CH2)2(CF2)7CF3] under acidic conditions in the presence of cetyltrimethylammonium chloride (CTACl) by sol–gel spin-coating. Calcination at 350 uC allowed the removal of surfactants without destroying the other organic content...
متن کاملThe Effect of thickness parameter and Fluorine Dopant on Photocatalytic performance of TiO2 thin films
In this study, Pure and doped titania sols with Fluorine (F/Ti:0.06) dopant, were prepared by sol-gel method and Ammonium Fluoride(NH4F) as the precursor. They were deposited on glass substrates (soda lime) in a certain(optimum) nanometric thickness by the dip coating method. Coated samples were dried and calcined under the specific rate. Phase composition and optical properties of coatings wer...
متن کاملMesoporous silicon oxynitride thin films.
Highly-ordered, pore-modified with amine groups, and glass-like mesoporous silicon oxynitride thin films were prepared by heat treatment of as-synthesized mesoporous silica thin films in a flowing ammonia environment at high temperatures.
متن کاملChloride capping of CdTiO3 for higher crystallinity and enhanced photocatalytic activity.
The crystallinity of cadmium titanate (CdTiO3) was greatly improved when synthesized under mild reaction conditions, in the presence of chloride. The highly crystalline CdTiO3 showed much enhanced photodegradation of methyl orange (MO) under simulated sunlight. CdTiO3 was characterized using X-ray diffraction (XRD), transmission electron microscopy (TEM), X-ray photoelectron spectroscopy (XPS),...
