✦ Synopsis

A number of applications of titanium dioxide including air and water cleaning rely on photocatalytic activity of its anatase form while others making use of UV-shielding and reflectivity properties employ rather the rutile form. Here we compare photoelectrochemical activity of TiO 2 films formed from nanocrystalline anatase and rutile particles of similar sizes and shapes. Particularly high incident photon-to-current conversion efficiencies observed for the oxidation of organic molecules at the anatase films contrast with the poor activity of the nanostructured rutile films.
