Abstract A series of iron/titanium oxide photocatalysts of varying Fe 3+ content have beenprepared by a number of different methods and subjected to controlled thermal treatment. Specimens have been characterised in terms of their crystalline structure and morphology, and indicate solid solutions containing both the anatase and rutile phases of TiO 2 , together with the formation of pseudo-brookite in some specimens. Intrinsic photo-activity measurements have been performed using a standard liquid-phase photocatalytic reaction. Results indicate that the photocatalytic activity of the specimens differs according to the method of preparation, and that all solids containing iron (III) species were less active than the parent titania, irrespective of whether or not they were true solid solutions; the solid solutions containing pseudo-brookite being less active than those which did not.
