The photodegradation of Acid Yellow 23 a model compound from monoazo textile dyes was investigated using TiO2, SnO2 and TiO2+SnO2 suspension as photocatalysts at different gap sizes. The results showed that the coupled particles were not much different from single TiO2 system at the gap size of 4.5 cm in a batch reactor. But the coupled system was more effective when the gap size was reduced to 2.5 cm. A complete decolorization occurs at the gap size of 1.1 cm after 20 min of irradiation while 90\% decolorization ...
