Abstract

Abstract: Performance and costs are considered as significant attributes for microbial fuel cells (MFCs). The performance of the anode and cathode electrode employed in the MFCs determined through redox reactions involved in transformation of chemical energy into electrical energy. Various research investigations intended to modify MFCs have acknowledged the importance of the electrode material in recent years. This review paper focused on modification in electrode and membrane materials of MFCs have been reported through incorporation of nanomaterials. Metal-based and carbon nanoparticles, as well as conductive polymers, may aid in the formation of thick microbial biofilms, resulting in improved electron transmission between biofilms and electrodes. Potential nanomaterials employed in MFCs modifications have important properties such as increasing active surface area, enhancing conductivity, and improving biocompatibility. Metal-based nano catalysts like as metal oxides and metal–organic frameworks among the several nano catalysts employed on the cathode side, are identified as high-performance and low-cost sustainable alternatives in comparison to the commonly utilized a very high-cost Pt. In addition, when compared to the commonly used and pricey Nafion, polymeric membranes treated with hydrophilic and antibacterial nanoparticles might result in improved proton conductivity and less biofouling.
