Abstract: TiO2 powder was incorporated into a polysiloxane matrix and this green body (GB) was pyrolysed at 1500°C, giving rise to a TiO 2-containing ceramic matrix composite (CMC). GB and CMC were analyzed by X-ray diffraction, density, total pore volume and average pore size determinations, scanning electron microscopy and UV-vis spectroscopy. The photocatalytic activity of GB and CMC was evaluated with respect to the photodegradation of salicylic acid (SA) in water, under UV radiation, by total organic carbon measurements. CMC promoted the photodegradation of 33 % of SA and it can be proposed as a promising alternative ceramic material for decontamination of water by heterogeneous photocatalysis.
