Abstract

The influence of transition metals, such as Ag, Cr, and Co, on the photocatalytic properties of titania-silica (TiO2-SiO2) prepared via both impregnation (imp) and photo-assisted deposition (PAD) methods has been investigated. The decomposition of 2-propanol under UV-light irradiation was used to probe the effect of transition metals deposition on the activity of titania-silica. PAD-Ag/TiO2-SiO2 prepared by the PAD method was highly active compared to the original TiO2-SiO2, while imp-Cr/TiO2-SiO2 prepared by conventional impregnation method showed a weak tendency toward the decomposition of 2-propanol.
