Research Progress on Preparation of TiO_2 Nanotubes by Anodic Oxidation on Porous Titanium Surfaces

多孔钛以其大比表面积、小比重、高强度引起了人们的关注。尤其是通过阳极氧化在多孔钛表面制备TiO_2纳米管,从而进一步增大多孔钛的比表面积,提高表面吸附性能,更成为今年研究的重点。阐述了阳极氧化法在多孔钛表面生纳米管结构的原理,综述了阳极氧化时不同参数变化对纳米管结构变化的影响,并从多孔钛性能、TiO_2纳米管的性能、阳极氧化形成机理角度,提出了当前研究中存在的问题,和今后作为催化剂载体潜在的发展方向。

The porous titanium with its large people＇s attention, especially the preparation of TiO2 Thus, increasing the specific surface area of porous become the focus study in this year. The principle of surface area, the small proportion and high strength has caused nanotubes on the surface of porous titanium by anodic oxidation. titanium and improving the surface adsorption performance have anodic oxidation method built nanotube structure on the surface of porous titanium was explained and effects of different parameters on the changes of nanotube structure were reviewed. From the aspects of properties of porous titanium and TiO2 nanotubes and formation mechanism of anodic oxidation, the existing problems in current research and future development direction were put forward.
