Effect of C60 on the Photocatalytic Activity of TiO2 Nanorods

C60-incorporated TiO2 nanorods were prepared in a hydrothermal process. Rhodamine B (RhB) as a model pollutant was used to probe the photocatalytic activity of products. The results showed that the photocatalytic activity of TiO2 nanorods incorporated with C60 under visible light irradiation markedly increased by a factor of approximately 3.3 when compared with pure TiO2 nanorods and approximately 2.7 when compared with Degussa P25, respectively. The enhanced photocatalytic activity under visible light irradiation may be ascribed to an effective separation of the photoexcited electrons due to the addition of C60.
