Paper Title:
Photocatalytic Activity of SiO2/TiO2 Supported on Glass Fiber under Vsible Light Irradiation
  Abstract

A SiO2/TiO2 supported on glass fibers photocatalyst with visible light activity were synthesized by sol-gel technology, butyl titanate as a Ti source, and tetraethylorthosilicate (TEOS) as a Si source. The photocatalytic activitie under visible light of SiO2/TiO2 supported on glass fibers were evaluated by the photocatalytic decomposition of methylene blue. The samples were characterized by scanning electron microscope (SEM), X-ray photoelectron spectroscopy (XPS), UV-Vis diffuse reflectance spectroscopy (UV-Vis-DRS). The results show that the optical absorption edges of the SiO2/TiO2 showed red shift with increasing the dopant of SiO2. The sample of SiO2/TiO2 supported on glass fiber (atomic ratio of Si/Ti=0.05) has the highest catalytic efficiency under visible light irradiation.
