Abstract
A simple approach for the synthesis of large quantities of silicon dioxide nanotubes with silver in inner wall was developed via sol-gel process at room temperature. Silver nitrate acted simultaneously as a template precursor and silver source during the process. Scanning electron microscopy and transmission electron microscopy images show that the nanotubes are 0.5–10 μm in length, and 200 nm in width. Energy dispersive X-Ray spectroscopy analysis results revealed the existence of S, Si, O, C and Ag in silicon dioxide nanotube. UV-Vis spectroscopy further revealed the existence of Ag by exhibiting the typical surface plasmon absorption maximum at 405 nm..
