The result showed that Ti02 nanowires with a diameter of 20 nm and a length up to several micron only can be synthesized in NH4F/glycol solution with a small amount of water (glycol: H20=39:1), 60V anodic voltage and 2h anodic time. The nanowires originated from the vertical splitting of anodically grown nanotubes.
