Carbon nanotube modified air-cathodes for electricity production in microbial fuel cells

► Carbon nanotubes (CNT) were used for the first time to modify MFC air-cathodes. ► CNT modified cathodes significantly increased electrochemical performance as well as MFC power density. ► CNT network provided more specific surface area for Pt catalyst and oxygen reduction. The use of air-cathodes... Full description

The use of air-cathodes in microbial fuel cells (MFCs) has been considered sustainable for large scale applications, but the performance of most current designs is limited by the low efficiency of the three-phase oxygen reduction on the cathode surface. In this study we developed carbon nanotube (CNT) modified air-cathodes to create a 3-D electrode network for increasing surface area, supporting more efficient catalytic reaction, and reducing the kinetic resistance. Compared with traditional carbon cloth cathodes, all nanotube modified cathodes showed higher performance in electrochemical response and power generation in MFCs. Reactors using carbon nanotube mat cathodes showed the maximum...
