摘要

Rapid exhaustion of non-renewable fuels due to industrialization has molded research to find a feasible approach by recycling wastewater. Incidentally, microbial fuel cells (MFCs) have appeared as a sustainable tool to treat wastewater and convert bioelectricity simultaneously. The limitations—microbial poisoning, electrode decay, and the potential drop in MFCs—make it unsuitable for high-energy applications. The fabrication of a polymer-metal organic framework (P-MOF)-supported electrode offers high conductivity, improved surface area, and substantial pore volume, resulting in significant MFC power output. The incorporation of MOF with polymer has improved the performance of the electrode owing to its remarkable electrochemical properties. This review highlights the essential insights into the sustainable development goals, emphasizing the physicochemical parameters and biocompatibility of polymer-MOF-modified electrodes. Moreover, the recent advances and the challenges of electrodes to be used in MFCs are discussed. Based on the assessment of power density, the hybrid electrodes could be a remarkable alternative in MFCs.
