Abstract (EN): This investigation reports the Possible use of carbon-supported manganese octahedral molecular sieves (OMS-2) for the electrooxidation of methanol. The effect of combining these materials with a commercially available 5%Ru-carbon sample is examined. The activity of the OMS-2 materials is evaluated with respect to other forms of manganese oxides such as pyrolusite and nsutite. The OMS-2 materials show a synergistic interaction with the 5%Ru-C as well as the pyrolusite materials that enhances their electrochemical activities effectively. These OMS-2 materials are not only cost-effective but also very electrochemically active. (c) 2005 Published by Elsevier B.V.
