Aerogel processing of MTi2O5 (MÂ =Â Mg, Mn, Fe, Co, Zn, Sn) compositions using single source precursors: synthesis, characterization and photocatalytic behavior

MgTi2O5 and the composites MTiO3/TiO2 (M = Fe, Co and Zn) were obtained from a single source precursor, (M[OTi(OPrn)3]2), by a modified aerogel process. Of these, CoTiO3/TiO2, decomposed acetaldehyde in the dark, at room temperature, while the other oxides behaved as regular UV photocatalysts.
