| 摘 要： | 为阻止纳米管钛酸在转变为新型锐钛矿TiO2时管状结构的破坏,先在纳米管钛酸的内、外表面化学吸附一层物质,用以保护纳米管钛酸在脱水转变为新型锐钛矿TiO2的过程中,管状结构不断裂、不塌陷,然后再除去表面的吸附物质,即可制得纯净的新型TiO2纳米管。新型TiO2纳米管有望应用于可见光"全"分解水制H2、药物缓释剂以及纳米反应器等研究。

| Abstract: | In this paper, chemical substances were chemically adsorbed on the inner and outer surface of nanotube titanium acid (NTA) to prevent the collapse of the nanotubular structure in the process of the transformation of the orthorhombic NTA to anatase TiO2. The pure novel anatase TiO2 nanotubes can be obtained by removal of the surface chemical substances. And these novel TiO2 nanotubes are hopefully used in the field of hydrogen production from visible light overall water splitting, drug delivery and nano-reactor. |
