Abstract: The process comprises treating 90-190 g titanium (IV) chloride in 10-100 ml de-ionized water for preparing Titanium cation (Ti4+); treating 130-275 ml potassium persulfate in 10-100 ml double-distilled water and keeping at constant temperature to obtain sulphate/oxide; dipping substrates into titanium (IV) chloride solution and re-dipping in de-ionized water to remove loosely bonded ions, if could be any; dipping substrates into potassium persulfate solution and re-dipping in de-ionized water to remove loosely bonded ions, if could be any, and keeping at 50-90° C. for complete one cycle; treating obtained Titanium cation (Ti4+) with sulphate/oxide and obtaining whitish layer on the substrate surface by necked eyes after about 10-15 cycles, suggesting initiation of film formation, wherein the deposition thickness of TiO2 layer is increased from 0.3-2.0-micron on determined 5-50 deposition cycles; and rinsing deposited films with de-ionized water and air annealed at 400-600° C. temperature to obtain anatase TiO2.
