Abstract

Uniform and highly adherent thin films of TiO2and Nd-TiO2were deposited on high silica fiber by sol-gel dip coating method in this study. The surface morphology and properties of synthesized composites films were characterized by XRD, SEM, TEM and XPS. The photocatalytic reactivity studies of TiO2and Nd-TiO2films were evaluated by photodegradation of the methyl orange (MO) under ultraviolet irradiation. The results shown that neodymium doped TiO2films have higher photodegradation efficiency than that pure TiO2films. The photocatalyst on high silica fiber have a higher photocatalytic activity compare to the glass due to it is light-guide fiber.
