Title: Carbon nanotubes-dispersed TiO{sub 2} nanoparticles with their enhanced photocatalytic activity

Graphical abstract: Carbon nanotubes-dispersed TiO{sub 2} nanoparticles with their enhanced photocatalytic activity. - Abstract: A novel carbon nanotubes (CNTs)-dispersed route is used to prepare high-activity titanium dioxide nanoparticles (TiO{sub 2}). Field-emission scanning electron microscopy and transmission electron microscopy reveals that the irregular TiO{sub 2} nanoparticles with diameters of 10–20 nm are highly dispersed. X-ray diffraction and specific surface area measurement show that high-activity anatase crystal is formed and the specific surface area of TiO{sub 2} nanoparticles is 147.36 m{sup 2}/g. The photoactivity of TiO{sub 2} was tested by photodegradation of Rhodamine B. The result shows that the photocatalytic activity of TiO{sub 2} nanoparticles prepared by the CNTs-dispersed route is three times higher than that by conventional hydrothermal treatment.
