  • The reduction and oxidation behaviour of manganese oxides .

    The reduction of manganese oxides with methane was studied to investigate the suitability of manganese as an oxygen storage compound. Manganese oxides are reduced by CH 4 to a lower-valent manganese oxide, producing CO 2 and water. Once the manganese oxide is reduced, it can be regenerated, i.e. reoxidised.
