Abstract: TiO2nanoparticle film catalysts with different thicknesses were prepared by plasma-enhanced chemical vapor deposition(PECVD) method and the surfaces were subsequently treated by TiCl4or O2plasma. Two kinds of TiO2films with different surface properties were obtained. Their surface microstructures and energy levels of surface states were tested by AFM, XRD, SPS. The photocatalytic activities of the catalysts were determined via photodegradation experiments of phenol. The results demonstrated that photocatalytic activities of samples whose surface was treated by O2plasma were greater than those treated by TiCl4plasma. Moreover, photodegradation ratio of phenol during the first hour catalyzed by 0.17 μm thickness TiO2nanoparticle film was greater than other samples. Especially, the difference of photocatalytic activities of TiO2nanoparticle films treated by TiCl4or O2plasma was respectively explained by energy band theory.

Key words: TiO2nanoparticle film, PECVD method, SPS, Surface state, Photocatalytic activity
