Abstract

WO3-TiO2 mixed oxides were synthesized by a sol-gel method employing an inorganic salt (Na2WO4 ∙ 2H2O) and an organic alkoxide (W(OC2H5)6), as tungsten precursors. Different results in terms of photoactivity in both formic acid mineralization in aqueous suspension and acetaldehyde oxidation in the gas phase were obtained, proving that the organic precursor may lead to the formation of an intimately mixed oxide with enhanced photoactivity in both reactions, also higher than that of pure TiO2 and of P25 TiO2.
