The Haber–Weiss cycle consists of the following two reactions:
H2O2 + OH.H2O + O2− + H+
H2O2 + O2−O2 + OH− + OH.
The second reaction achieved notoriety as a possible source of
hydroxyl radicals. However, it has a negligible rate constant
. It is
believed that iron(III) complexes can catalyse this reaction: first,
Fe(III) is reduced by superoxide, followed by oxidation
