Synthesis and Photocatalytic Activity of Ag Doped TiO₂ Nanofibers

Abstract:

Ag/TiO₂ nanofibers were obtained by sol-gel method combined with uniaxial electrospinning. The effects of different sintering temperatures (400°C, 500°C, 600°C) and different concentrations of silver (0 wt%, 0.5 wt%, 1.0 wt%, 1.5 wt%) on photocatalytic activity of TiO₂ were investigated. The morphology and interface interaction of the Ag/TiO₂ composites were investigated by SEM, TEM, XRD and UV-visible spectrophotometer. The experimental results showed that the diameter of the fiber sintered at 400°C is about 120 nm and the fiber is composed of 10-20 nm small particles. The degradation rate of methylene blue was 71% for the Ag/TiO₂ composites fiber with 1.0wt% silver and sintered at 400°C.
