Abstract: The demand for alternative energy sources from non-recyclable waste materials will be a hot research topic in future industries. This interest is primarily due to the ability to harness energy from waste materials, the provision of localized power solutions, and the promotion of efficient power conversation. In this respect, Microbial Fuel Cells (MFC) represent new energy sources possessing unique qualities for many applications. MFC generates power by utilising exoelectrogens forming the biofilm on the surface of the anode. Since in the MFC, wastewater is primarily converted into protons and electrons at the anode surface, where biofilms typically develop, the anode becomes the most vital component. Consequently, significant research has been conducted on anode material to improve MFC performance. The present review focuses on different aspects of the MFC, including a comprehensive summary of the recent developments in the field of MFCs, including a state-of-the-art literature review based on a bibliometric analysis using keywords, a description of the mechanism and operational principle of MFC, applications and a summary of current research perspectives including the use of carbon nanotubes, graphene, graphitic carbon nitride, MXene, and their nanocomposites as anode materials with stable power density performance. Lastly, we present the challenges and future perspectives regarding the continued development of MFC anode materials, culminating in overall conclusions related to MFC research.
