Biographical Information about Author(s)

We used voltammetry, bulk electrolysis (BE), and x-ray diffraction (XRD) analysis to assess the viability of various Mn2Oy redox systems for the production of H2 in electrolytic cells. We determined that the Mn3O4/Mn2O3 system is not appropriate for H2 production, primarily because of solubility issues. We determined that the MnO/MnO2 system is also not viable as a source of H2 as a fuel, because the current density is too low and the potential at which the oxidation occurs is too close to the thermodynamic value for conventional electrolysis. However, the MnO/MnO2 system is potentially viable for producing MnO2 or H2 as chemical commodities.
