International audienceWe 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, well-crystallized thin films of anatase TiO2 are tailored under potentiostatic control at -1.5 V (vs. AgCl/Ag) / 100 degrees C followed by a rapid post-annealing treatment at 500 degrees C in air
