Abstract

Previous work by Ko showed the wet-end application of Zeolite in combination with TiO₂ to produce sufficient photocatalytic activity to degrade toluene. The removal efficiency was greater than that of several commercial non- Zeolite based photocatalytic papers. The current research sought to further the work of Ko, by studying the photocatalytic activity of Zeolite-based TiO₂ in coatings. The ratio of Zeolite and TiO₂ were varied along with the type of latex binder used. The optical, as well as the photocatalytic activity, were studied. Brightness decreased with increasing Zeolite use, due to the impure zeolite available. Rutile can increase the brightness. With the same Zeolite ratio, the samples with rutile can also give higher opacity.
