    摘要： A preparation method for nano titanate, nano titanic acid, and nano TiO 2 . A Ti-T intermetallic compound, as a titanium source, is reacted with an alkaline solution under ambient pressure at a temperature near the boiling point of the alkaline solution, enabling the efficient preparation of titanate nanofilm materials under normal pressure. On this basis, it is possible to economically produce titanic acid nanofilm materials and TiO 2 nanosheet/powder. In combination with subsequent high-temperature and high-pressure reaction, titanate nanotubes, titanic acid nanotubes, and TiO 2 nanotubes/rods can be efficiently prepared. The preparation method provided herein has simple operation and low cost, and can prepare various nano titanate, nano titanic acid and nano titanium dioxide materials, including nanofilms and nanotubes/rods, exhibiting good application prospects in the fields of polymer-based nanocomposite materials, ceramic materials, photocatalytic materials, hydrolysis-based hydrogen production, hydrophobic materials, sewage degradation materials, bactericidal coatings, anti-corrosion paints, and marine paints.
