Electrocatalysis of oxygen reduction at well-defined iron oxide electrodes

A comparative study of O2 reduction on well defined iron oxides Fe3O4 and γ-FeOOH is presented. The Fe(III)/Fe(II) surface stoichiometry strongly depends on potential and determines the electronic conductivity and electron transfer rate to soluble redox species. A common feature of O2 reduction on b...
