Titanium-based material is one of the most studied materials due to its unique properties and wide potential application in many elds (Chen and Mao 2007; Roy et al. 2011; Chen et al. 2013). For many of these applications, it is very important to manipulate their morphology, crystalline texture, and surface characteristics for better control of the properties. Especially, 1D and 2D titanium-based nanostructures, such as nanotubes, nanorods, and nanosheets, which have

high surface-to-volume ratio and excellent electronic transport property, are of great interest. e detailed introduction to 1D and 2D titanium-based nanostructures can be found in review articles (Chen et al. 2011; Léonard and Talin 2011; Liu and Liu 2012).
