abstract The preparation procedure of silica-titania composite oxide using novel solution/sol single precursor containing titanium peroxocomplex and silicic acid has been described. Pechini-type sol-gel process has been used to prepare oxides from the aqueous precursor. Some structural, morphological and textural characteristics of the prepared material have been presented. Composite SiO2/TiO2 has high surface area (c.a. 300 m(2)/g), and it is composed of anatase nanoparticles with the mean diameter of 5 nm embedded in amorphous silica, then TiO2 prepared via similar method is presented as a mixture of anatase and rutile phases. The proposed synthetic procedure meets the requirements of "green chemistry".
