Haber-Weiss reaction
Haber-Weiss Reaction is a mechanism for copper to catalyze the formation of oxygen radicals.
Cu2+ + O2– → Cu+ + O2 Cu+ + H2O2 → Cu2+ + OH• + OH– Net: H2O2 + O2– → OH• + OH– + O2
The Haber-Weiss reaction consists of a Fenton reaction coupled with a reaction between oxidized metal ion and superoxide, the superoxide thus serving to recycle the metal through its Fenton-active, reduced state.[1]
