“…Recently, a 3D flower-like metal organic material (3DHFLM), Zn/Co-S-3DHFLM showed enhanced ORR activity in MFC with 172.8 maximum power density and 93% COD removal efficiency 467.35 mW m -2 . The synergistic effect of the bimetallic active center and the sulfur has greatly enhanced the ORR activity of the Zn/Co-S-3DHFLM catalyst (Lu et al, 2023). Besides, the NiCo 2 S 4 /NiCo 2 O 4 @NSC electrocatalyst showed excellent ORR performances in MFC application which showed around 1.2 and 1.7 times the enhanced maximum power density of 831.74 mW m -2 compared to the NiCo 2 O 4 @NSC, and N-C catalysts, respectively.…”

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

“…[4][5][6] Pt and Pt-based catalysts are well known for their outstanding ORR activity, but their resource scarcity and prohibitive cost greatly limit their widespread commercial application. [7][8][9][10][11] Therefore, it is necessary to develop efficient synthesis and implementation methods for nonplatinum-group metal (non-PGM) materials as cathode catalysts in MFCs.…”
