Abstract

The mechanism of the Fe³⁺-ion-catalyzed oxygen evolution from H₂O₂ was investigated. The reaction proceeds through two intermediates. Oxygen is evolved by the reduction of the second intermediate FeO³⁺ by H₂O₂. Both O₂ and the catalyst are liberated in this process, probably without the intermediate formation of free radicals. The rate constant of this step is proportional to [H⁺]^-1. It was concluded that HO₂^- is the reactive form of H₂O₂ and that the reduction consists of a transfer of H^- ions.
