Preparation of TiO₂ Precursor Solution:
Dissolve 0.1N titanium tetraisopropoxide (TTIP) in 20 mL of ethanol.
Stir the solution continuously for 30 minutes using a magnetic stirrer to ensure complete dissolution.
Dispersion and Hydrothermal Treatment:
Add a few drops of distilled water to create a dispersion medium.
Subject the solution to ultrasonication in a bath for 20 minutes to enhance uniformity.
Transfer the well-mixed solution into a Teflon-lined stainless-steel autoclave.
Heat the autoclave at 150°C for 3 hours to facilitate the formation of TiO₂ nanoparticles
Purification and Drying Process:
Allow the autoclave to cool naturally to room temperature.
Wash the precipitate thoroughly with deionized water to remove impurities.
Use a centrifuge to separate the nanosheets.
Heat Treatment for Crystallization:
Dry the sample in a vacuum oven at 110°C for 5 hours.
Follow this with heating in a muffle furnace at 500°C for 2 hours to enhance crystallinity.
Allow the sample to cool slowly to ensure proper structure formation.
Final Collection:
Collect the synthesized TiO₂ nanoparticles (NPs) for further analysis and applications.
