Highly efficient, photoactive, nanocrystalline TiO 2 powder was prepared with the help of modified sol-gel method. The prepared nanomaterials were characterized by modern techniques such as, TG-DTA, XRD, FE-SEM, EDX, TEM, BET surface area and FT-IR analysis for the identification of phase structure, phase composition and morphology. Formation of thermally stable, nanocrystalline, highley photocatalytic active, tetragonal anatase Titania was confirmed by TGA-DTA, XRD and HR-TEM. Similarly, FE-SEM confirms spherical, cauliflower like morphology for all Titania samples prepared with different cationic surfactants. The presence of mesoporous Titania was also confirmed by N 2 adsorption-desorption. The effect of addition of various surfactants significantly improves the photocatalytic activity. Prepared nanomaterials were successfully tested under UV-Vis light region for photodegradation of Methyl Red (MR) dye material which is act as water pollutant. The C 16 TAB assisted Titania exhibits enhance photocatalytic efficiency as compared to industrially applied photocatalyst, Titania (Degussa P25) and zinc oxide under similar experimental condition.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
