Abstract : TiO 2 samples doped with platinum oxide were obtained by using a sol-gel low temperature approach. The photocatalytic oxidation of CO in the presence of O 2 was monitored to study the influence of the Pt doping on the photocatalytic degradation performance of TiO 2. The obtained results were compared with those obtained with TiO 2 Degussa (P-25). Photocatalytic studies of the prepared mesoporous Pt/TiO 2 nanoparticles for the photooxidation of CO revealed notable photocatalytic activity, which was 3 times higher than that of Pt photodeposited onto commercial TiO 2 Degussa P-25. Also quantum yield for CO 2 formation for mesoporous Pt/TiO 2 calcined at 500 °C is higher than that of Pt photodeposited onto commercial TiO 2 Degussa P-25 by about three times. The structure and textural properties Pt/TiO 2 were studied by X-ray powder diffraction (XRD), N 2 adsorption (BET), Transmission electron microscopy (TEM) and UV.
