Anatase TiO₂ nanocrystals

TBT (97%, 25 mL) and HF (Extra High Grade, 4 mL) are added into ethanol (25 mL) in a Teflon beaker (in an ice bath) in a dropwise manner (slowly) under vigorous stirring.
The solution is then transferred into a Teflon lined autoclave and then the autoclave is tightly sealed. Subsequently, the autoclave is put into an oven at 200 °C and kept for 27 h.
The precipitates are collected after filtering, washing (ethanol and distilled water) and drying at 80 °C.
