Effect of C₆₀ on the Photocatalytic Activity of TiO₂ Nanorods

Abstract

C 60 -incorporated TiO 2 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 TiO 2 nanorods incorporated with C 60 under visible light irradiation markedly increased by a factor of approximately 3.3 when compared with pure TiO 2 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 C 60 .

Effect of Fe3+ doping on the performance of TiO2 mechanocoated alumina bead photocatalysts

“…In recent years, many studies have been reported involving the use of TiO 2 -based photocatalyst due to the physical and chemical stability, low cost, non-toxicity and unique electronic and optical properties of titania [1][2][3][4].…”

Au/ZnO nanocomposites: Facile fabrication and enhanced photocatalytic activity for degradation of benzene

“…The result indicates that Au nanoparticles supported on ZnO nanowires enhance the photocatalytic ability of ZnO nanowires for benzene degradation. On the basis of previous studies, the most reasonable rationalization, which is similar to that in the C 60 /ZnO (or TiO 2 ) composites photocatalysis [30,37,38], is shown in Scheme 2. In the first step, in this case, ZnO nanowires were excited by UV light with larger energy than the bandgap (3.37 eV) of ZnO leading to the generation of electrons in the semiconductor conduction band and holes in valence band.…”

Nanocarbons with Different Dimensions as Noble-Metal-Free Co-Catalysts for Photocatalysts

“…Long et al [39] synthesized C 60 nanoparticles incorporated TiO 2 nanorods. The photocatalytic activity of C 60 /TiO 2 nanorods is about 3.3 times higher than that of TiO 2 nanorods.…”
