Effects of Solvent on the Structure and Properties of Titanium Dioxide Nanoparticles and Their Antibacterial Activity
Titanium dioxide is semiconductor metal oxide having many applications in photocatalytic activities, cosmetics and in the food industry. It exists in three major crystalline forms: anatase, rutile and brookite. The solvents play a major role in the synthesis, stability and morphology of the metal oxide nanoparticles. It affects both the phase and particle size of metal oxide. T...
متن کاملSynthesis of Nano-Sized Titania Particles by Hydrolysis of Titanium Tetrachloride
Nano-sized titanium dioxide TiO2 powder was successfully prepared from its precursor titanium (IV) chloride by a simple and new wet chemical method. TiCl4 were used as precursor in hydrogen peroxide, H2O2 and ethanol. This solution was then peptized using nitric acid and heated under reflux at 80°C. Their physico-chemical properties were then characterized by transmission electron microscopy (T...
