Since platinum nanoparticles are known to enhance the photocatalytic activity, they were introduced into the TiO(2) mesopores by pulsed electrodeposition. Additionally, sandwich-like layers with up to five alternating TiO(2) and Pt layers were prepared. The photocatalytic gas-phase oxidation of acetaldehyde served as a test reaction to characterize the activity in the gas phase of both pristine TiO(2) as well as Pt/TiO(2) single-and multilayer films. The ordered mesoporous pristine TiO(2) and Pt/TiO(2) nanocomposites exhibited significantly higher photoactivity than commercial Pilkington Activ (TM) glass and dense TiO(2) films.
