Nanoscale manganese dioxide particles supported onto carbon nanotubes (MnO2/CNTs) were prepared through a microwave-assisted reduction method and used as a catalyst for oxygen reduction reaction (ORR) in an alkaline environment. The MnO2 with high crystallinity and nanosized birnessite-type was obtained by microwave irradiated for 60 s repeating 3 times. Especially, the MnO2/CNTs exhibited a positive...
