Heterogeneous photocatalysis is studied in the field of environment recovery by the total degradation of organic and inorganic pollutants and for the synthesis of chemicals. In the present chapter, the basic principles of photocatalysis are discussed together with the advantages and disadvantages related to its coupling with a membrane separation in photocatalytic membrane reactors (PMRs). The types of membranes used and their criteria of selection are briefly examined. On the base of their configuration and membrane operation, PMRs can be used in reactions of photodegradation of pollutants and reactions of synthesis, evidencing as the appropriate choice of the configuration is a key step because of large-scale implementation. Some case studies in water treatment (i.e., pharmaceuticals removal) and the reaction of synthesis (CO2 reduction) are discussed, evidencing potentialities, drawbacks, and future trends.
