Heterogeneous photocatalysis belongs to the very well-known AdvancedOxidation/Reduction Processes (AOPs/ARPs), valuable technologies for purification and2remediation of water and air. These processes are based on the use of some form of energyto produce highly reactive species, which in turn are able to promote oxidations orreductions on the target pollutants; the main oxidative species is the hydroxyl radical, HO,which has the ability to attack most of the organic and inorganic chemical species [1-6].Several excellent revisions exist on the subject, with different approaches, many of themreferred specifically to heterogeneous photocatalysis [2,7-10]. However, in what follows, abrief revision of heterogeneous photocatalysis will be given.
