THE NATURE OF THE OXIDATION REDUCTION STEP IN THE CATALYTIC DECOMPOSITION OF HYDROGEN PEROXIDE BY FERRIC IONS.
Abstract
The mechanism of the Fe3+ ion catalyzed oxygen evolution from H2O2 was investigated. The reaction proceed through two intermediates. Oxygen is evolved by the reduction of the second intermediate FeO3+ by H2O2 in the fourth step of the mechanism. Free radicals are not formed as transient products of this step. Thus both O2 and the catalyst are liberated in it. The constant K-4 is proportional to the inverse of H(+) concentration. It was concluded that HO2(-) is the reactive species and the reduction consists of a transfer of H(-) ions. (Author)
