Abstract

The method for preparing fluorine-doped lamellar black TiO2 nanomaterials includes mixing a solution of tetra-n-butyl titanate, n-propanol and hydrofluoric acid together, and then stir the solutions for a period of time. The solution is transferred into an autoclave and reacts at a certain temperature for a period of time. The sample obtained by the reaction is washed and dried. Then, the sample is heated in a protective atmosphere for a period of time so as to produce the fluorine-doped lamellar black TiO2 nanomaterials. This fluorine-doped lamellar black TiO2 owns superior optical absorption and electron transport performances.
