By a News Reporter-Staff News Editor at Biotech Week -- Investigators discuss new findings in Nanotubes. According to news reporting from Jeonju, South Korea, by NewsRx journalists, research stated, "Nanotubular shaped alpha-MnO2/graphene oxide nanocomposites were synthesized via a simple, cost and time efficient hydrothermal method. The growth of hollow structured MnO2 nanotubes preferentially occurred along the  direction as evidenced from the morphological and structural characterizations."
The news correspondents obtained a quote from the research from Chonbuk National University, "The tunnels of alpha-MnO2 nanotubes easily accommodated the molecular oxygen and exhibited excellent catalytic activity towards the oxygen reduction reaction over the rod structure and was further enhanced with the effective carbon support graphene oxide. The MnO2 nanotubes/graphene oxide nanocomposite modified electrode exhibited a maximum power density of 3359 mW m(-2) which is 7.8 fold higher than that of unmodified electrode and comparable with the Pt/C modified electrode. The microbial fuel cell equipped with MnO2 nanotubes/graphene oxide nanocomposite modified cathode exhibited quick start up and excellent durability over the studied electrodes and is attributed to the high surface area and number of active sites."
According to the news reporters, the research concluded: "These findings not only provide the fundamental studies on carbon supported low-dimensional transition-metal oxides but also open up the new possibilities of their applications in green energy devices."
