Bibliometric Overview of Research on Materials for Microbial Fuel Cells: Catalysts and Coatings as Key Factors for Efficiency

Abstract:

Microbial fuel cells (MFCs) offer a sustainable solution for converting organic waste into electricity through electroactive microorganisms. However, their widespread implementation is hindered by low catalytic efficiency and the high cost of noble metal-based electrodes. This study addresses these challenges by conducting a comprehensive bibliometric analysis of research trends and scientific advances in MFC materials, with a focus on catalysts and electrode coatings as key determinants of system performance. Using analytical tools such as VOSviewer and RStudio, we systematically mapped publication trends, collaboration networks, and technological developments from 2007 to 2025. Beyond bibliometric metrics, the analysis highlights significant scientific breakthroughs, including the development of a CeO₂/Co₃O₄-PEDOT/CF nanocomposite anode, which increased voltage output by 74.9% and power density by 2.5-fold, and a Ni-Fe LDH/(DSP) cathode system that achieved 83.5% contaminant removal efficiency with notable antimicrobial activity. These findings demonstrate the potential of metal oxide-based and doped materials to replace costly platinum while maintaining high electrochemical performance. Furthermore, the integration of nanotechnology and artificial intelligence in material design is identified as an emerging trend driving future innovations. The study concludes that advancing MFC technology toward practical applications in wastewater treatment and decentralized energy systems will require enhanced global collaboration and the adoption of scalable, cost-effective materials.
