Abstract

The production of hydrogen from water using ceramic semiconductors with photocatalytic properties has gained special relevance in the last years, due to their potential use for the generation of hydrogen in a direct and clean way. Doping with transition metals has demonstrated to be an effective method to obtain new active photocatalysts in the visible range of the solar spectrum by changing the band gap of the material. In this paper we study the effect of the addition of various dopants (Fe, Ni, Cr, Mn, Co, Cu) in the structure and band gap of Bi4Ti3O12, in order to improve its photocatalytic activity and make it visible light active. Accordingly, doped BIT based materials have been obtained by solid state processing and different amounts of an additional phase with sillenite structure, Bi12TiO20, have been detected. With the dopant a shift of the absorption spectra is produced towards higher wavelengths and consequently towards lower band gap values. The band gap values obtained for many of the prepared compositions are quite promising, promoting the study of their catalytic properties.
