摘要:

高度有序TiO2纳米管阵列由于具有结构的有序性及尺寸的可控性,已成为近年来光催化材料领域的研究热点之一。本文针对有序TiO2纳米管阵列特殊的结构形貌特点,阐述了管壁粗糙度、管长、管壁厚度、管径及表面积对其光催化性能的影响。在不同的催化剂载体(透明玻璃基底、无基底、钛丝网基底、非平面钛片基底)生长TiO2纳米管阵列是有效地提高其光催化性能的途径之一,介绍了这些新型结构的TiO2纳米管阵列的研究进展。最后总结了现阶段主要掺杂改性TiO2纳米管阵列的方法及掺杂效果。在此基础上,指出了当前研究中存在的主要问题,并展望今后的研究方向。

Abstract:

Highly ordered TiO2 nanotube arrays have attracted increasing interest due to its highly ordered structure and convenient control of its size. Due to the unique nanotubular structurethe key factors affecting the photocatalytic activity are discussed in terms of morphology and geometrysuch as tube roughnesstube lengthwall thicknesstube diameter and surface area. Highly ordered TiO2 nanotube arrays grown on different substratessuch as transparent glassesfree-standingTi meshes and non-planar Ti foilsare the important ways to improve photocatalytic activityand the progress of these new types of TiO2 nanotube arrays is reviewed. In additiondifferent doping methods and their effects on the TiO2 nanotube arrays with various elements are summarized. The existing problems are discussed and further research prospects are proposed.
