Abstract
Highly crystalline TiO2 anatase nanoparticles were synthesized via gel–sol method by using titanium isopropoxide and triethanolamine The products were characterized by Xray diffraction transmission electron microscopy thermogravimetric/differential thermal analysis and nitrogen gas absorption methods The particle size ranged from 7 to 24 nm having specific surface area of 64 to 220 m2/g Selective TiOH4 gel specifications and hydrothermal test conditions resulted in thermodynamicallystable phaseformation Aging at 130°C for 4 h resulted in particle size of 7 nm while at 130 and 160°C for 12 h resulted in 12 and 21 nm respectively
