A NOVEL METHOD OF PREPARING AND FIXING TiO_2 NANOMETER PARTICLES

摘要

It is well known that during the past two decades, TiO_2 has become an important subject. But its separation and recollection have limited its further commercial applications, especially in photoelectro-chemistry field. Thus, its preparation has become a key problem in its recent study. Tetrabutyl titanate has been used as materials in many TiO_2 synthesis methods, but obviously, it is too expensive comparing with titanium tetrachloride we introduced and employed in this paper. To the best of our knowledge, for the preparation of TiO_2, there is no paper reporting the method carried out in liquid phse and ambient pressure, where titanium tetrachloride was utilized to low down the cost. The aim of this paper is to show a low cost method of preparing different structures TiO_2 nanometer particles, which was performed in liquid and ambient pressure. Encouragingly, the novel TiO_2 nanoporous film electrode produced from these TiO_2 nanometer particle exhibited satisfactory results in the photo-electro oxidation of methanol, which is meaningful to widen TiO_2 application.
