Haber–Weiss reaction

https://doi.org/10.1351/goldbook.HT06787
The Haber–Weiss cycle consists of the following two reactions:,H2O2 + OH.-->H2O + O2 + H+ and,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 by dihydrogen peroxide.
