求教：TiO2纳米管的结构和形貌。
|
||
|
想模拟构建TiO2纳米管， 但是看了许多的文章，结构基本都是实验上的电镜图。 大家能否推荐一些关于TiO2纳米管或纳米结构形貌描述的文章。 谢谢了先！ [ Last edited by rabbit7708 on 2008-1-24 at 16:26 ] |

Formation Mechanism of H2Ti3O7 Nanotubes Phys. Rev. Lett. 91, 256103 (2003) Formation mechanism of H2Ti3O7 nanotubes by single-step reaction of crystalline TiO2 and NaOH has been investigated via transmission electron microscopy examinations of series specimens with different reaction times and extensive ab initio calculations. It was found that the growth mechanism includes several steps. Crystalline TiO2 reacts with NaOH, forming a highly disordered phase, which recrystallized into some H2Ti3O7 thin plates. H-deficiency on the top surface leads to an asymmetrical environment for the surface Ti3O72- layer. The calculations of the surface tension, elastic strain energy, interlayer coupling energy, and Coulomb force indicated that the asymmetrical environment is the principal driving force of the cleavage of the single sheets of H2Ti3O7 from the plates and the formation of the multiwall spiral nanotubes. Bottom-Up Assembly of Single-Domain Titania Nanosheets on (1×2)-Pt(110) Phys. Rev. Lett. 97, 156101 (2006) A bottom-up route towards the synthesis of titania nanosheets is explored, alternative to the exfoliation of layered titanates. Nanosheets are assembled from the constituent elements and epitaxially matched to a suitable substrate: (1×2)-Pt(110). Their basic lepidocrocite structure is modulated at the nanoscale due to coincidence with the substrate. Density functional calculations reveal the structure details of the nanosheet, which is also shown to be in close relationship with a (001)-oriented anatase bilayer. |
