Abstract:The characteristics,types,developments of the heterogeneous photocatalytic reactors were presented. The design and application of novel reactors were described on the basis of photon transfer limitations and mass transfer limitations. parison of the slurry and supported reactors showed that the divided slurry and supported fluidized bed photocatalytic reactor were the development trends of photocatalytic reactors. In particular,important issues in design and research trends in the future were discussed.
Keywords:TiO2;photocatalysis;slurry photocatalytic reactor;supported photocatalytic reactor
