Activated carbon supported Fe–Cu–NC as an efficient cathode catalyst for a microbial fuel cell

Abstract

Microbial fuel cell (MFC) is a promising device for converting bioenergy into electrical energy, but its performance is mainly limited by the slow kinetics of oxygen reduction reaction (ORR). Hence,...

Nanopolyhedral Zn/Fe-NC derived from bimetallic zeolitic imidazole frameworks as an efficient catalyst for the oxygen reduction reaction in an air-cathode microbial fuel cell

“…[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.…”

Dopamine-coated layered Co0.85Se as an efficient bifunctional oxygen electrocatalyst

“…On the other hand, they also suffer from a lack of dual functions and poor stability. [17][18][19][20][21][22] Therefore, it is urgent to design and synthesize non-precious catalysts that are earth-abundant, cost-effective active, stable, and bifunctional.…”

The electron modulation effect on metal nanoclusters of Fe-N-C based bifunctional electrocatalysts

“…Previous works reported that the multi-atom sites exhibit enhanced ORR performance because of the atomic pair effects [21][22][23][24]. The paired atom sites such as Fe-Cu or Fe-Co would change the bonding energy of the active sites (Fe-N 4 sites for example) and bene tted the absorption/desorption of the intermediates [25]. However, the nanoclusters of metals on carbon-based materials are hard to be distinguished and characterized, which is because of the aggregation of the metal elements and the movement and the deformation of the electrocatalysts during the ORR process [26][27].…”
