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

High‐power microbial‐fuel‐based hybrid cells with three‐dimensional graphene‐coated iron foam as an anode control Fe³⁺ release

SmartMat, Journal Year: 2024, Volume and Issue: unknown

Published: Jan. 16, 2024

Abstract Microbial fuel cells (MFCs) benefit from the introduction of iron in anode, as its multiple valence states and high electron‐catalytic activity led to improved power densities MFCs. However, effect long‐term Fe 3+ release into electrolyte on density MFCs is often overlooked. Herein, an anode consisting a three‐dimensional foam uniformly coated by reduced graphene oxide (rGO/IF) with suitable loading (8 g/m 2 ) large specific surface area (0.05 m /g) for high‐density bacterial was prepared. The hybrid based rGO/IF exhibit maximum 5330 ± 76 mW/m contributed galvanic cells. enables continuous during discharging As result, showed 2107 64 after four cycles, facilitated through reversible conversion between 2+ accelerate electron transfer efficiency. results indicate that can be used designing fabricating high‐power optimizing rate electrolyte.

Electrospinning Mo-Doped Carbon Nanofibers as an Anode to Simultaneously Boost Bioelectrocatalysis and Extracellular Electron Transfer in Microbial Fuel Cells

Materials, Journal Year: 2023, Volume and Issue: 16(6), P. 2479 - 2479

Published: March 21, 2023

The sluggish electron transfer at the interface of microorganisms and an electrode is a bottleneck increasing output power density microbial fuel cells (MFCs). Mo-doped carbon nanofibers (Mo-CNFs) prepared with electrostatic spinning high-temperature carbonization are used as anode in MFCs here. Results clearly indicate that Mo2C nanoparticles uniformly anchored on nanowire, anodes could accelerate rate. Mo-CNF ΙΙ delivered maximal 1287.38 mW m−2, which was twice unmodified CNFs anode. This fantastic improvement mechanism attributed to fact Mo doped unique nanofiber surface enhance colonization, electrocatalytic activity, large reaction areas, not only enable direct transfer, but also promote flavin-like mediated indirect transfer. work provides new insights into application electrospinning technology preparation materials scale.
