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