The Photoelectrochemical Behavior of Ferric Oxide in the Presence of Redox Reagents

Abstract
The influence of dissolved sulfide ion and the ferri/ferrocyanide redox system on the photoelectrochemical behavior of iron oxide has been investigated. Particular attention was given to transient behavior and to dark current phenomena. An interpretation of the results is given in terms of a back‐reaction of photogenerated species with conduction band electrons via surface states.
