TiO2 hollow nanostructures were successfully synthesized by a controlled hydrothermal precipitation reaction using Resorcinol-Formaldehyde resin spheres as templates in aqueous solution, and then removal of the RF resins spheres by calcination in air at 450 °C for 4 h. The obtained TiO2 hollow spheres were characterized by X-ray diffraction, scanning electron microscopy, transmission electron microscopy, N2 adsorption-desorption analysis, and UV-visible diffuse reflectance spectroscopy. The photocatalytic activity of the as-prepared samples was evaluated by photocatalytic decolorization of rhodamine B aqueous solution at ambient temperature under UV illumination. The results indicated TiO2 hollow nanostructures exhibit the excellent photocatalytic activity probably due to the unique hollow micro-architectures. © 2012 Elsevier Ltd and Techna Group S.r.l.
