Nanostructured titanic acid salts and preparation process and use thereof

The present invention provides a nanostructured titanic acid salt and a preparation process and use thereof. The process comprises preparing a dispersion containing titanium peroxy complex; slowly adding a metal compound to the dispersion containing the titanium peroxy complex to form a solution; adding an alcohol to the solution under normal temperature and normal pressure to produce the nanostructured titanic acid salt precursor precipitate in the solution, and separating the precipitate to obtain the titanic acid salt precursor; drying the precursor, and then heat treating it to obtain the nanostructured titanic acid salt product. The present invention provides a process for preparing a titanic acid salt with simple preparation process, easy control for process parameters and easy large-scale industrial production.
