Charge separation characteristics of a high-activity, mixed-phase titania photocatalyst (Degussa P25) are probed by EPR spectroscopy. While previous proposals consider rutile as a passive electron sink hindering recombination in anatase, this research details the critical and active role of rutile in TiO 2 formulations. The inactivity of pure-phase rutile is …
Degussa (Evonik) TiO 2 P25 consisting of a mixture of anatase and rutile crystallites is a well-known commercial material with high photocatalytic efficiency. The mixture of anatase and rutile phases in P25 is reportedly more active than the individual polymorphs of TiO 2.Contrary to this viewpoint, we demonstrate that H 2-reduced rutile TiO 2 is much more …
