Reduced mediator Electron donor / Reducing environment Oxidized mediator Pollutant (in high oxidation state electron acceptor) Reduced less toxic compound Figure 1. The reductive transformation catalytic cycle. The oxidative pathway utilizing nanomaterials is related to a family of methods called Advanced Oxidation Processes (AOPs) (13-14). These methods involve in-situ generation of active radical species such as hydroxyl or superoxide radicals. This can be achieved by addition of chemical oxidants such as oxygen, ozone or Fenton's reagent (hydrogen peroxide and iron salts), or by employment of an energy source, usually UV irradiation, directly on the contaminants, or in conjugation with an oxidizing agent such as UV/O3 or UV/H2O2.
