Using polystyrene (PSt) particles as template, PSt/TiO2composite particles with AgCl incorporation were prepared through hydrolysis of tetrabutyl titanate in the presence of AgNO3and NaCl. AgCl doped TiO2hollow particles were successfully prepared with the PSt/TiO2composite microspheres pretreated at 180°C followed by calcination. The morphology of PSt/TiO2particles and the crystal structures of the AgCl doped TiO2hollow particles were characterized. The photocatalytic activity of the doped TiO2hollow particles in degradation of Rhodamine B was tested under UV and visible lights and compared to that with Ag doped TiO2particles. The results showed that TiO2hollow particles, either doped with Ag or AgCl, demonstrated higher photocatalytic activity than the pure TiO2particles. This enhancement in photocatalytic activity was more significant with AgCl doped TiO2than that with Ag doped, and more distinct when the degradation was done under visible light than that under UV light.
