Abstract:

Microbial fuel cell (MFC) is a novel bioelectrochemical device that uses a biocatalyst to convert chemical energy stored in organic wastewater into electrical energy. However, multiple factors limit the practical applications of MFCs, such as the high cost of electrode production and their low conversion efficiencies of power density and energy. Therefore, improving the catalytic performance of the electrodes and lowering the cost of electrode production have become focuses in MFC research. Because of the excellent electrical conductivity and catalytic properties of graphene-based hybrid materials, the development of these electrode materials for use in MFCs has attracted much attention. This review summarizes recent advances of graphene-based hybrid electrodes in MFCs. The preparation methods and the catalytic performance of graphene-modified electrodes, metal and non-metallic/graphene hybrid electrodes, metal oxide/graphene hybrid electrodes, polymer/graphene hybrid electrodes, and graphene gel electrodes are discussed in detail. The influence of graphene-based hybrid anodes and cathodes on the electricity generation performance of MFCs is analyzed. Finally, the problems facing graphene-based hybrid electrodes for MFCs are summarized, and the application prospects of MFCs are considered.
