Response surface methodology to investigate the comparison of two carbon-based air cathodes for bio-electrochemical systems.

Bio-electrochemical technologies can generate renewable electrical bioenergy from the oxidation of organic materials through the catalytic reactions of the microorganisms while treating the wastewater. In this study, the use of carbon aerogel as a novel catalyst with high porosity (the total pore volume of 1.84 cm g) and high surface area (491.
