TiO2 is a fascinating material proving its usefulness in a wide range of applications. In catalytic and electrochemical applications, it has been utilized as a stable semiconductor electrode for the conversion of solar energy into chemical or electrical energy. Especially, the cleavage of water over TiO2 using light energy is well known. The degradation of organic pollutants present in waste water, using irradiated dispersions of TiO2, is a fast growing field in basic and applied research. One can also mention that the use of TiO2 in pigments sun lotions and toothpastes and its biocompatibility. The EC phenomena of TiO2 had been reported first by Inoue et al., who produced the films by hydrolysis of titanium tetraoxide. The film show cathodic coloration and turned dark blue.
The LPD-TiO2 film deposited at 40 ¢J with (NH4)2TiF6 for 0.1 M and 0.2 M for boric acid. The films were transparent in visible range and can be colored in a solution 1M LiClO4 + propylene carbonate. The deposition rate can be controlled perfectly about 43 nm/h. The 270-nm thickness LPD-TiO2 film gives the best transmittance difference at 550 nm.
