Outline of microbial fuel cells technology and their significant developments, challenges, and prospects of oxygen reduction electrocatalysts

Frontiers in Chemical Engineering, Journal Year: 2023, Volume and Issue: 5

Published: Sept. 7, 2023

The microbial fuel cells (MFCs) which demonstrates simultaneous production of electricity and wastewater treatment have been considered as one the potential greener energy technology among available bioelectrochemical systems. air-cathode MFCs gained additional benefits due to using air avoiding any chemical substances catholyte in cathode chamber. sluggish oxygen reduction reaction (ORR) kinetics at is main obstacles achieve high cell (MFC) performances. Platinum (Pt) most widely used efficient ORR electrocatalysts its more stable acidic media. Because cost easily poisoned nature Pt, several attempts, such a combination Pt with other materials, non-precious metals non-metals based has demonstrated. However, practical application MFC not yet achieved mainly slow ORR. Therefore, review draws attention develop choosing suitable materials should be urgent for applications MFCs. In this article, we present an overview technology, then some significant advancements precious metals-based catalysts (very briefly), metals-based, carbon-based, biocatalysts remarks on corresponding results applications. Lastly, also discussed challenges prospects

Study on the performance of biochar prepared from walnut shell and traditional graphene electrode plate in the treatment of domestic sewage in microbial fuel cells

Water Science & Technology, Journal Year: 2024, Volume and Issue: 89(11), P. 2880 - 2893

Published: May 21, 2024

ABSTRACT As a new pollutant treatment technology, microbial fuel cell (MFC) has broad prospect. In this article, the devices assembled using walnut shells are named biochar-microbial (B-MFC), and graphene graphene-microbial (G-MFC). Under condition of an external resistance 1,000 Ω, B-MFC with biochar as electrode plate can generate voltage up to 75.26 mV. The maximum power density is 76.61 mW/m2, total internal 3,117.09 Ω. removal efficiency for ammonia nitrogen (NH3-N), chemical oxygen demand (COD), (TN), phosphorus (TP) was higher than that G-MFC. results analysis showed there more operational taxonomic unit (OTU) on shell plate. final two materials BET specific surface area testing method (BET) scanning electron microscope (SEM) pore size smaller, larger, distribution smoother. show make plates optional waste recycling excellent development prospects.
