摘要：

Nanoparticles of titanium dioxide (TiO2) were prepared by the sol-gel method and characterized by XRD, TEM, FTIR and UV-Visible absorption spectroscopy for their structure, morphology and particle size. Organization, stabilization of the nanoparticles of TiO2 from further growth, and partially inhibiting the photodegradation was achieved by capping with polymers. Photodegradation of dye on TiO2 nanoparticles encapsulated in different polymers has been studied by diffused reflectance UV spectroscopy. The role of the polymer on the photodegradation of TiO2 has been compared and explained. (C) 2001 Elsevier Science Ltd. All rights reserved.
