One step preparation of highly dispersed TiO₂ nanoparticles

Abstract

A facile approach was developed to prepare highly dispersed TiO₂ nanoparticles with selected phase. The crystallization phase of the nanoparticles can be easily tuned from anatase to rutile by the dosage of hydrochloric acid in the reaction system. The crystallite size of the as-prepared anatase TiO₂ nanoparticles was ca. 3.2 nm with high dispersion. A transparent TiO₂ colloid was obtained by dispersing the as-prepared anatase TiO₂ nanoparticles in deionized water without any organic additives added. The concentration of TiO₂-H₂O colloid can be as high as 1600 g/L. The optical transmittance of TiO₂-H₂O colloid with a low concentration was nearly 100% in the visible region. Furthermore, anatase TiO₂ nanoparticles(TiO₂-NPs) showed superior photocatalytic performance compared to rutile TiO₂-NPs.
