Abstract :
Titanium dioxide nanocrystals were synthesized by sol-gel method at room temperature. Titanium isoprophoxide
and absolute ethanol were used as precursors to prepare the sol. The pH of the solution was adjusted by adding
nitric acid and sodium hydroxide solution. The prepared TiO2 nanocrystals were annealed at 325°C, 425°C and
525°C respectively. The effect of pH on the surface morphology and structural properties of TiO2 nanocrystals
were studied.
