摘要：

In this paper, we surveyed the effect of the concentration of AgNO3 solution and the time of photoreduction on the formation of Ag nanoparticles supported on TiO2 nanotubes (Ag/TNTs) were synthesized by photoreduction method. Their morphology and crystal structure were determined by Transmission Electron Microscopy images (TEM), X-ray Diffraction (XRD) and Energy-dispersive X-ray spectroscopy (EDX) data. Results show that the amount of Ag nanoparticles supported on TNTs could be controlled by changing of the illumination time (photoreduction time) and the concentration of AgNO3 solution. Besides, the annealing temperature has a direct influence on the morphology of TNTs. Especially, the nanotubes transformed into nanorods at 500 degrees C for 2 hours.
