AbstractAbstract
[en] The laser ablation technique known as Pulsed Laser Deposition (PLD) is used for obtaining thin films of TiO2/SnO2, which was later modified with Co3O4 by PLD or by sol-gel technique. The films were characterized by X-ray diffraction, ultraviolet Vis and Raman spectroscopies, scanning electron microscopy and energy analysis of the dispersed X-rays produced by Auger decay. The anatase phase with particles of nano metric size was obtained by depositing the titanium dioxide in argon atmosphere. The Co3O4 films obtained by PLD on the TiO2 showed the same morphology. The electrocatalytic activity of the films that were used as photo anodes for the reaction of oxygen liberation was carried out in the darkness, with environment light and the light emitted by a xenon lamp. The current density was higher for films of Co3O4/TiO2/SnO2 obtained by PLD that for cobalt dioxide of mixed valence obtained by sol-gel. (Author)
