Title
Doping TiO2 with p-block elements: Effects on photocatalytic activity
Abstract

A critical overview is presented on the role that first row p-block elements boron, carbon, nitrogen and fluorine, employed as dopants of TiO2, have in improving the capability of this photocatalyst in harvesting solar light for photocatalytic applications. The peculiar physicochemical properties of doped TiO2 materials are described in terms of the results of both theoretical calculations and photocatalytic efficiency tests, in relation to their bulk and surface features. The limitations of doping titania with non metal elements are outlined and a few recent examples of very promising co-doping effects are discussed.

► The photocatalytic activity of non metal doped TiO2 has been reviewed. ► The review is focused on doping TiO2 with first row p-block elements N, C, B, F. ► Recent theoretical studies on TiO2 doping with such elements is also reviewed. ► Visible light absorption by doped materials does not guarantee photoactivity. ► Co-doping titania with non metals appears more promising than single doping.
