摘要
综述了TiO2纳米粉末和纳米管的主要制备方法并进行了比较,提出了今后制备技术的发展方向。同时总结了通过理论计算来进行材料设计的基本思路,着重强调使用固体能带和分子轨道理论以及能谱实验数据相结合的方法来进行成分设计和进一步提高计算水平,更好地反映材料性能的电子结构本质。
This article is focused on the present status of preparation methods of the nanopowder and nanotubes of TiO2, and points out the development direction of preparation of such materials. The basic ways of the theoretical calculation and parts of calculated results are summarised. It is emphasised that the methods combining band theory and molecular orbital theory with energy spectrum measurement can explain related experimental phenomena and direct the design of experiment.
