Abstract: 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°C for 3h. 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 films. [Copyright &y& Elsevier]
