Thick film titania photocatalysts (50-100 mu m. Degussa P-25 TiO2) coated on two types of soda glass supports viz. beads (TiO2/B) and Rasching rings (TiO2/R) were tested in vapour phase photodegradation of toluene (63-383 g m(-3)), acetone (116-1161 g m(-3)), and ethanol (116-1161 g m(-3)) in a batch recirculation photoreactor at 60-70 degrees C. The concentrations of the substrates were 10- to 100-fold higher than those reported previously in similar investigations. The films were characterized by using SEM for morphology and EDX for elemental composition and mapping. Further, the effects of water vapour and shape and packing of the glass supports on the photodegradation kinetics were examined. The TiO2 films on both the glass supports demonstrated high activity for photodegradation of toluene, acetone, and ethanol according to first-order kinetics.
