We report on the electrodeposition of TiO2 upon transparent conducting oxide (ITO) by using a milder electrochemical bath based on room-temperature ionic liquids (1-ethyl-3-methyl imidazolium-bis(trifluoromethylsulfonyl)imide)) and titanium butoxide as a soluble precursor. By taking advantage of oxygen reduction which proceeds about 500 mV before titanium +IV reduction, wellcrystallized thin films of anatase TiO2 are tailored under potentiostatic control at −1.5 V (vs. AgCl/Ag) / 100◦C followed by a rapid post-annealing treatment at 500◦C in air.
