摘要

通过水热法合成了一系列二氧化钛纳米管。通过改变制备条件，制备出了具有不同形态或纹理特性的纳米管。利用各种表征技术阐明了所制备纳米管的各种特征。比表面积在 200 至 230 m2/g 之间的样品在降解甲酸时表现出最大的光催化活性。对结构特征的详细分析强调了表面结构缺陷在调整光催化性能方面所起的复杂作用，从而有助于实现最佳的光氧化活性。

Highly efficient TiO2 nanotubes for photocatalytic degradation reactions through optimization of textural properties

A series of titanium dioxide nanotubes were synthesized via a hydrothermal method. By varying the preparation conditions, nanotubes with different morphologies or textural properties were produced. Various characterization techniques were used to clarify the various features of the as-prepared nanotubes. Samples with surface areas ranging between 200 and 230 m²/g in specific surface area exhibit the maximum photocatalytic activity in the degradation of formic acid. Detailed analysis of the structural characteristics emphasizes the complex role played by surface structural defects in the tuning of their photocatalytic performance helping in this way to achieve optimal activity in photooxidation.
