(a) Anatase (101) lattice and (b) rolling-up direction and process of nanotubes, with a and b denoting primitive translation vectors, and θ referring to chiral angle. (c)–(g) Different chiral structures of anatase (101) nanotubes. Solid red circle denotes oxygen atom and solid blue circle represents titanium atom. Radius of each nanotube is about 15 nm.
