Abstract

Manganese oxides (MnO x ) catalysts were chemically deposited onto various high specific surface area carbons. The MnO x /C electrocatalysts were characterised using a rotating disk electrode and found to be promising as alternative, non-platinised, catalysts for the oxygen reduction reaction (ORR) in neutral pH solution. As such they were considered suitable as cathode materials for microbial fuel cells (MFCs). Metal [Ni, Mg] ion doped MnO x /C, exhibited greater activity towards the ORR than the un-doped MnO x /C. Divalent metals favour oxygen bond splitting and thus orientate the ORR mechanism towards the 4-electron reduction, yielding less peroxide as an intermediate. © 2008 Springer Science+Business Media B.V.
