The preparation and selected properties of Mg-doped p-type iron oxide as a photocathode for the photoelectrolysis of water using visible light

Abstract

Stable Mg-doped iron oxides that exhibit p-type character have been synthesized. These have been utilized in the form of sintered polycrystalline disks for the photodissociation of water. We report the influence of sintering temperature, surface oxygen deficiency, Mg-doping level, and solution chemistry on the photoactivity of the Mg-doped iron oxide photocathodes.
