Silver nanoparticles are widely used as catalyst for the degradation of organic contaminants like phenol and its derivatives, this is due to their small size which translated in high surface area, strong redox properties and their ability to generate reactive oxygen species (ROS) . AgNPs acts as electron mediator and donor which facilitates oxidation and reduction reactions, resulting in breaking down of phenols into smaller less harmful compounds . AgNPs enables the transfer of electrons between oxidants such as hydrogen peroxide or dissolved oxygen and phenol molecules . This promotes the generation of ROS such as hydroxyl radicals (-OH) and superoxide radicals (O2 -) which breaks the aromatic ring of phenol by attacking it predominantly at ortho and para position due to their high electron density . AgNPs can facilitate reduction of oxidants such as hydrogen peroxide (H2O2) or Ferric ion by acting as an electron donor . In Fenton-like reaction Fe 3+ is reduced to Fe 2+ which is essential for the generation of hydroxyl radicals which accelerates phenol degradation . Fenton reaction, results in catechol ring opening which converts catechol into muconioc acid that is further oxidized to maleic and fumaric acid . As the Fe and H2O2 concentration is high, all the intermediates convert to formic acid which then oxidizes to non-toxic CO2 and H2O in water bodies . Fig 1 . Illustrates the mechanism of phenolic degradation by Fenton-like reaction by using AgNPs.
