TiO 2因具有化学稳定性高、无毒、材料成本低、良好的生物相容性和独特的半导体性能,广泛应用于能量转化和存储、催化剂载体以及生物组织工程等领域。通过阳极氧化法制备的TiO 2纳米管阵列是一种定向排列的有序结构,可以通过调整工艺参数实现结构控制。该技术经历了4个发展阶段:1在含有氢氟酸的水溶液中,采用直流阳极氧化技术,在金属钛表面制备TiO 2纳米管阵列,长度仅数百纳米;2在含有氟化物的水溶液中,采用同样方法在 TiO 2 is widely used in energy conversion and storage, catalyst carrier and biological tissue engineering for its high chemical stability, non-toxicity, low material cost, good biocompatibility and unique semiconductor properties. The TiO 2 nanotube array fabricated by anodization is an ordered and ordered structure, which can be controlled by adjusting the process parameters. The technology has undergone four stages of development: 1 in the aqueous solution containing hydrofluoric acid, the use of DC anodic oxidation technology to prepare TiO 2 nanotube arrays on the surface of titanium metal, the length of only a few hundred nanometers; 2 in a fluoride-containing aqueous solution , Using the same method in
