Abstract
The present invention relates to a method for preparing a nano-titanate, a nano-titanic acid and a nano-TiO2 containing doping E or embedding E nanoparticles, and the use thereof. By using an E-doped Ti-T intermetallic compound as a titanium source, and reacting it with alkaline solution at atmospheric pressure and near its boiling-point temperature, an E-doped titanate nanofilm is prepared with high efficiency and in a short time. Through acid treatment and (or) heat treatment, a titanate nanofilm containing embedding E nanoparticles, an E-doped titanic acid nanofilm, and a titanic acid nanofilm and a TiO2 flake powder containing embedding E nanoparticles can be further prepared. Through a subsequent reaction at high temperature and pressure, the preparation of an E-doped titanate nanotubes and titanic acid nanotubes, and titanic acid nanotubes and TiO2 nanotubes/nanorods containing embedding E nanoparticles can be achieved in high efficiency and low-cost.
