Kimberly Gray and Kevin Schwartzenberg from Northwestern University present an overview on the synthesis, characterisation and applications of titania nanotubes from a photocatalytic angle in this Hot Perspective. A greater appreciation of the different properties of the inner and outer surfaces of titania nanotubes will aid the fundamental understanding of chemical, optical and electrical processes occurring in applications such as for solar fuel production.
