Preparation of Photocatalytic Activity Nanosized TiO2 from Metatitanic Acid
以正钛酸为原料制备纳米TiO2光催化剂

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.
