Abstract: Nanosized TiO2 particles were prepared by using the direct hydrolysis means from metatitanic acid. The specimens were characterized by transmission electron microscopy (TEM), X-ray diffractometry, differential thermal analysis. Nanosized TiO2 of mixing anatase and rutile prepared was found to show good photocatalytic properties in the photodegredation of anionic sodium dodecylbenzensulfonate surfactant, compared with P-25.

Key words: nanosized TiO2, photodegredation, metatitanic acid
