Abstract: | We report a facile method to grow multi-sectional TiO2 nanotube arrays consisting of alternating bamboo-shaped and smooth-walled nanotube sections by anodization.Two key factors are necessary for obtaining these morphologies.First,in order to avoid possible disruptions between the conjoint sections of the nanotube,the distribution of hydrogen ions is suggested not to be fiercely disturbed when switching from the first to the second stage.Second,to avoid the disruption of the nanotube at the joint which resu... |
