In this work is reported the performance of TiO2 and TiO2/clinoptilolite composites (with weight proportions of 1/99, 10/90, 99/1 and 90/10) synthesized by the sol-gel technique, in the adsorption and photocatalytic degradation of MV 2B dye (MV-2B). The materials were supported on glass substrates and mounted on tubular reactors coupled to CPC solar concentrator with two different geometric concentration ratios. The photocatalyzer powders were characterized by X-ray diffraction, transmission electron microscopy (TEM) and the BET method for surface area determination; the material deposits were characterized by profilometry and scanning electronic microscopy (SEM). The results showed that the incorporation of clinoptololite improved the quality of the materials deposit on glass substrates by bringing a better adherence and also increased the efficiency of the degradation process by up 10%.
