Heterogeneous photocatalysis is an advanced oxidation process largely studied in the field of environment recovery by the total degradation of organic and inorganic pollutants and for synthesis. In this chapter, the basic principles of photocatalysis are discussed with the advantages related to its coupling with a membrane separation in photocatalytic membrane reactors (PMRs). The types of membranes most widely used and their criteria of selection are briefly discussed. PMRs’ classification based on their configuration and on the type of membrane operation is also discussed, evidencing as their appropriate choice is a key step in view of large-scale implementation. Finally, some case studies in water treatment (i.e. pharmaceutical removal) are discussed, with potentialities, drawbacks, and future trends.

Abstract
Heterogeneous photocatalysis is an advanced oxidation process largely studied in the field of environment recovery by the total degradation of organic and inorganic pollutants and for synthesis. In this chapter, the basic principles of photocatalysis are discussed with the advantages related to its coupling with a membrane separation in photocatalytic membrane reactors (PMRs). The types of membranes most widely used and their criteria of selection are briefly discussed. PMRs’ classification based on their configuration and on the type of membrane operation is also discussed, evidencing as their appropriate choice is a key step in view of large-scale implementation. Finally, some case studies in water treatment (i.e. pharmaceutical removal) are discussed, with potentialities, drawbacks, and future trends.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
