Synthesis of Porous Spheres of TiO₂ Nanoparticles and its Photocatalysis Behavior for 1-Naphthylamine-4-Azobenzene-4'-Sulfonic Acid

Abstract:

Porous spheres of TiO₂ nanoparticles have been successfully prepared using cationic monomer as precursory solid and thermal decomposition at 500 ^oC. The product was characterized by X-ray powder diffraction and scanning electron microscope. The ultraviolet photocatalytic activity of the obtained materials was evaluated by decomposing 1-naphthylamine-4-azobenzene-4'-sulfonic acid. The porous spheric TiO₂ exhibited a good photocatalytic activity. The degradation rate was about 96.5% for in contaminated water after 50 min irradiation by UV light.
