| Abstract: | In this paper,TiO2 nanowires were fabricated by a facile hydrothermal method.The Ag nanoparticles were loaded on TiO2 nanowires by reduction of Ag(NH3)+2 in the presence of glucose solution.The as-synthesized Ag/TiO2 nanowires were characterized by TEM,HRTEM,XPS and UV-Vis spectra.The results show that the Ag nanoparticles were well dispersed on the external surface of the TiO2 nanowires.UV-visible absorption measurements show that the as-synthesized Ag/TiO2 nanowires present strong absorption in visible li... |
