	<span lang=\"EN-US\">Heterogeneous
photocatalysis is one of the advanced oxidation processes (AOP¡¯s). These are
very used nowadays for their implementation in tertiary water treatment with
solar activation, with very good results. In this study, TiO<sub>2</sub> porous
films were synthesized by sol-gel method. Polyethylene glycol (PEG) 4000 was
used as a templating reagent, which is oxidized at a lower temperature than TiO<sub>2</sub>.
This allows the formation of a ¡°skeleton¡± of porous TiO<sub>2</sub> with
increased surface area, resulting in higher photocatalytic activity. The film
characterization was made with help of FE-SEM microscope, XRD diffractometer
and scotch tape test. Finally, the oxidation experiments were performed using
methylene blue as a model pollutant and they revealed an increase in the
photocatalytic activity of porous films in comparison with the non-porous
films.</span>
