Researchers at Chonbuk National University Target Science [Enhanced electrical contact of microbes using Fe(3)O(4)/CNT nanocomposite anode in mediator-less microbial fuel cell]

By a News Reporter-Staff News Editor at Science Letter -- Investigators discuss new findings in Science. According to news originating from Jeonju, South Korea, by NewsRx correspondents, research stated, "A novel Fe(3)O(4)/CNT nanocomposite was synthesized and employed for the modification of carbon paper anode in a mediator-less microbial fuel cell (MFC) to enhance its performance. The Fe(3)O(4)/CNT composite modified anodes with various Fe(3)O(4) contents were investigated to find the optimum ratio of the nanocomposite for the best MFC performance."

Our news journalists obtained a quote from the research from Chonbuk National University, "The Fe(3)O(4)/CNT modified anodes produced much higher power densities than unmodified carbon anode and the 30wt% Fe3O4/CNT modified anode exhibited a maximum power density of 830mW/m2. In the Fe(3)O(4)/CNT composite modified anode, Fe(3)O(4) helps to attach the CNT on anode surface by its magnetic attraction and forms a multi layered network, whereas CNT offers a better nanostructure environment for bacterial growth and helps electron transfer from E.coli to electrode resulting in the increase in the current production with the catalytic activity of bacteria."

According to the news editors, the research concluded: "The electrocatalytic behavior and all possible mechanism for their better performance are discussed in detail with the help of various structural and electrochemical techniques."
