Hydrothermally synthesized TiO2 nanotubes and nanosheets for photocatalytic degradation of color yellow sunset

TiO2 nanotubes and nanosheets were synthesized from commercially available spherical TiO2 nanoparticles by hydrothermal method. All samples were characterized by XRD and TEM. Colour yellow sunset ( E110) was used to test the photocatalytic activity of the prepared samples, it was found that all morphologies (spherical particles, nanotubes and nanosheets) were able to decompose E110 completely, where the TiO2 nanotubes showed the highest photocatalytic activity. It was found also that the photodeposition of Ag particles on TiO2 particles decreased the time required for complete degradation of E110.
