| Abstract: | Titanium dioxide(TiO2) nanowires were synthesized by one-step hydrothermal method using tetrabutyl titanate,isopropanol and sodium hydroxide as starting materials.The synthesized TiO2 nanowires were characterized by scanning electron microscopy(SEM),X-ray diffraction(XRD) and energy dispersive X-ray spectrometry(EDX).The effects of reaction temperature,concentration of sodium hydroxide and reaction time on the formation of the nanowires were investigated.It is found that the optimum reaction temperature,con... |
