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).
