Catalytic advancements in carbonaceous materials for bio-energy generation in microbial fuel cells: a review

Magnesium Cobaltite Embedded in Corncob-Derived Nitrogen-Doped Carbon as a Cathode Catalyst for Power Generation in Microbial Fuel Cells

“…A major part of the MFC cost contributes to electrodes, especially the cathode material, that can directly affect the ORR kinetics, electron transfer rate, and power generation from MFCs. Cobalt has been extensively explored as the cathode material owing to its ability to enhance the surface area, improve the catalytic activity of composites toward ORR, and reduce the charge transfer resistance at trace concentrations. , However, Co is a regulated chemical in aqueous solutions, and its high Co content could lead to Co pollution in aqueous solutions, causing the poisoning of microorganisms . To avoid Co pollution, cobalt oxide-based composites have successfully been used, but at the cost of higher resistance than Co, which lowers the electron transfer efficiency for energy generation .…”

“…2 Inquests for efficient and robust energy materials, carbons, metal oxides, metal composites, polymer layered composites, etc., have been explored to construct highly active composite electrocatalysts. 3 Consequently, materials with diverse morphology, surface properties, conductivity, active site density, and oxidation/reduction potential are essential for developing cathode electrocatalysts. Carbonaceous materials with high electrical conductivity have been widely explored for ORR.…”

“…Carbonaceous materials are relevant to a wide range of applications including, among others, water treatment, 1 CO 2 capture, [2][3][4][5][6][7][8][9] catalysis, [10][11][12] novel electrode materials, 13 and sensing. 14,15 Their properties can be tuned and enhanced by incorporation of heteroatoms.…”

Functionalised graphite felt anodes for enhanced power generation in membrane-less soil microbial fuel cells

“…The anode material influences the development of the electroactive biofilm and, therefore, the overall performance of the SMFC 8 . Carbonaceous materials, including carbon paper, carbon felt, and graphite felt, have been extensively exploited in microbial fuel cells [9][10][11] . Carbon electrodes are preferred over metal-based ones in microbial fuel cells due to their high biocompatibility, specific surface area and roughness that promote attachment and growth of biofilm, as well as guaranteeing the cost-effectiveness of the resulting device [12][13][14] .…”

“…8 Carbonaceous materials, including carbon paper, carbon felt, and graphite felt, have been extensively exploited in microbial fuel cells. [9][10][11] In microbial fuel cells, carbon electrodes are preferred over metal-based ones as they are cost-effective and also facilitate the attachment and growth of biolms, due to their high biocompatibility, specic surface area and roughness. [12][13][14] In SMFCs, carbon-based additives such as biochar 15 and carbon bers 16 can be added to the soil to overcome charge transfer limitations.…”
