Abstract

A new class of anatase TiO₂ films consisting of octahedral pyramidal nanocrystals via slow oxidative hydrolysis was studied. Well-defined octahedral pyramidal nanocrystals, which are close to equilibrium shape of anatase TiO₂, were oriented with [001] axis preferably perpendicular to the substrate. The unique structure of octahedral pyramidal nanocrystals in the TiO₂ film led to anatase (101) surface as the most accessible surface, which may be used in specific site-selective catalysis. The anatase TiO₂ film with a new morphology consisting of octahedral pyramidal nanocrystals was an exciting addition to a family of TiO₂ films. Because of unique chemical, physical and optical properties of TiO₂, this new class of TiO₂ films are of great interest for sensor, photovoltaic, and other applications. This is an abstract of a paper presented at the AIChE Annual Meeting (San Francisco, CA 11/12-17/2006).
