摘要：

We report a dry process to produce a multilayered TiO2 film which has the rutile phase on an anatase substrate, for highly activated photocatalysis. Ar ion beam irradiation changes the anatase surface into rutile at 500 degrees C, which is less than the crystallization temperature of rutile from anatase (600 degrees C). The ion beam modification makes it possible to form rutile thin him on anatase. The multilayered structure should be a promising photocatalyst, theoretically.
