In this study, different titania films were prepared by a sol-gel spin-coating technique. By introducing nanocarbon spheres into the precursor solution, porous titania film was prepared after calcination at a temperature of 500 degrees C for 3 h. The as-prepared porous titania film was characterized by XRD, BET, TEM and SEM. The photocatalytic property of the prepared porous film was evaluated by degrading X-3B under UV irradiation. Results showed that photocatalytic performance of as-prepared porous film was much higher than that of smooth titania and P25. lms. (C) 2008 Elsevier B.V. All rights reserved.
