摘要
Titanium dioxide (TiO 2 ) nanoarchitecture has been widely used in the environmental and energy related applications. Herein, a simple and facile synthesis method will be introduced for high-conversion preparation of TiO 2 nanotubes using hydrothermal method from nanoscale TiO 2 particles. The quantity of TiO 2 nanoparticles being used towards the formation of nanotubes was investigated using FESEM, TEM and EDX. In the present study, TiO 2 nanoparticles were treated chemically with NaOH aqueous solution and subsequently with HCl aqueous solution under optimum experimental condition. It was found that the TiO 2 nanotubes with outer diameter of 10 nm were successfully formed. In this case, the amount of residual Na + ions during the hydrothermal synthesis stage can be controlled by HCl treatment, which resulted in the formation of one-dimensional TiO 2 nanotubes.
