Abstract

Pd modified TiO2 displayed an increased light harvesting potential into the visible region of the solar spectrum by 8% and an enhanced photocatalytic decolorization rate of rhodamine B by a factor of 19 compared to bare TiO2. A red-shift in the light harvesting ability of the catalyst means that there is photochemical activity present for excitations up to 600 nm. We attribute this enhanced photo-reactivity to a localized plasmon associated with nanostructured Pd that we photochemically deposited onto TiO2 prior to dye decolorization. This catalyst system has significant potential to treat environmental pollution via solar energy harvesting.
