CABRERA, Saúl et al. SILICOTITANATOS SINTETIZADOS POR LA RUTA DE LOS ATRANOS APTOS PARA LA OXIDACION FOTOCATALITICA DEL FENOL. Rev. Bol. Quim [online]. 2007, vol.24, n.1, pp.33-37. ISSN 0250-5460.

ABSTRACT The TiO₂ and a novel binary oxide SiO/TiO2 was prepared by a new modified sol-gel method using atrane route were triethanolamine is a complex reagent acting how hydrolysis retarding has been favorably the homogeneity distribution in the oxide SiO₂/TiO₂ and your photocatalytic activity was investigated to phenol oxidation. The factors, such as the calcinations temperature of synthesis of oxide TiO₂ and the ratio of SiO₂:TiO₂ in photocatalyst activity was investigated.  It was showed that the TiO₂ obtained at 600°C with high content of anatase structure has a better activity what TiO₂ P25 Degussa. The additions of SiO₂ enhance your activity significantly for phenol elimination in function of adsorption properties

Keywords : Silicotitanatos; Atran; synthesis; phenol; photocatalytic oxidation.
