Silver nanowires were synthesized simply by thermal or photo reduction of silver nitrate solution on anatase TiO@sub 2@ films without any capping and reduction agent. The silver nanowires were 1-50 µm in length and 20-150 nm in diameter. Several parameters including reduction temperature, light energy and intensity, reduction time and the concentration and amount of the silver nitrate solution affected the formation of silver nanostructures. Scanning electron microscopy, transmission electron microscopy, X-Ray diffraction, and UV-Visible spectroscopy were used to characterize the silver nanostructures. The results provided a better understanding of the growth mechanism of silver nanowires formed by this simple route.
