THE FABRICATION OF Ag NANOPARTICLES LOADED TiO2 NANOTUBES BY PHOTOREDUCTION METHOD AND THEIR PHOTOCATALYTIC ACTIVITY

Abstract

In this paper, we survey the effect of the photoreduction (illumination) time and the annealing temperature on the formation of Ag nanoparticles supported on TiO 2 nanotubes (Ag/TNTs). The morphology, crystal structure and compositions were characterized by transmission electron microscopy (TEM), X-ray diffraction (XRD) and energy-dispersive X-ray spectroscopy (EDS), respectively. The results showed that Ag nanoparticles are supported on TNTs and the amount of Ag nanoparticles could be controlled. The morphology of TNTs can be changed by the photoreduction time and the annealing temperature.
