Why is anatase a better photocatalyst than rutile? - Model studies on epitaxial TiO2 films
Scientific Reports, 2014 The prototypical photocatalyst TiO2 exists in different polymorphs, the most common forms are the anatase- and rutile-crystal structures. Generally, anatase is more active than rutile, but no consensus exists to explain this difference.

Structure of a model TiO2 photocatalytic interface [PDF]
, 2016 The interaction of water with TiO2 is crucial to many of its practical applications, including photocatalytic water splitting. Following the first demonstration of this phenomenon 40 years ago there have been numerous studies of the rutile single-crystal
