Revitalizing microbial fuel cells: A comprehensive review on the transformative role of iron-based materials in electrode design and catalyst development

Popis výsledku v původním jazyce

Microbial fuel cells (MFCs) face substantial challenges, including electrode cost, biofouling, and slow kinetics of the oxygen reduction reaction (ORR) at the cathode. This review examines iron-based (Fe-based) materials as electrodes and catalysts, emphasizing their efficacy in pollutant degradation and electricity generation. As anode modifiers, Fe-based materials enhance electrical energy production by improving electron transport, increasing anode voltage, and promoting microbial adhesion. At the cathode, they facilitate a more efficient 4-electron transfer process for the ORR, reducing undesirable hydrogen peroxide formation. This review discusses the impact of Fe and N dispersion, surface, and active site optimization on ORR activity and stability, highlighting the advantages of Fe-based materials in terms of stability, reproducibility, and biocompatibility through multi- element doping and nanoscale interface engineering. These modifications enable Fe-based materials to outperform traditional Pt/C catalysts in power density. The role of microbial communities, including Geobacter and Pseudomonas, , in electron transfer and wastewater treatment in Fe-based MFCs is also addressed. Additionally, the potential of artificial intelligence (AI) to optimize operational and catalyst performance in enhancing Fe-based MFC efficiency is explored. This review concludes with a comprehensive assessment of Fe-based materials in MFCs, focusing on their contributions to sustainable energy and water purification by examining bioelectricity generation, fabrication costs, and power output, thereby providing a holistic overview of the advancement of Fe- based materials for environmentally sustainable applications.
