“…Their high electronic conductivity and low double-layer capacitance limit the residual currents and increase the sensitivity of the electrochemical measurements [122]. It has been evaluated that the gold-sputtered carbon paper as anode in MFC could accelerate biofilm growth [123].…”

“…The peak current of CV in the MFCs using treated carbon powder cathode was higher than those where carbon powder without any treatment was used as cathode. Also, reduction peaks (at -0.25 V) with the nitrogen doped cathodes (for both MFC-2 and MFC-4) were much higher than that of normal carbon cathodes, after 10 cycles of operation, demonstrating NDCP cathode had a higher faradic charge capacity, which is known to be related to the electrode surface area [25]. After 10 cycles (Fig.…”

Long term stable performance of a microbial fuel cell (MFC) is difficult to achieve because of scale formation on cathode. Nitrogen doped carbon powder (NDCP) was used as cathode along with amino-trimethylene-phosphate (ATMP) as an anti-scaling agent in a MFC. Maximum power density of 66 mW/m 2 obtained in the MFC using NDCP as cathode, was 2.2 times higher than that obtained with simple carbon powder. High electroactive surface area and meso-porous structure of the NDCP improved electrochemical performance of the MFC having NDCP cathode. After 40 days of operation, the maximum power density decreased by only 12.5% in the MFC using NDCP and having ATMP in its cathode as compared to a 55.6% decrease in the MFC using only carbon powder in cathode due to fouling. Ultrathin shell structure of NDCP catalyst molecules, as evident from transmission electron microscopy (TEM) images, ensured high catalyst performance providing good electron transfer for enhancing oxygen reduction reaction (ORR). Less deposition of calcite molecules on cathode surface, illustrated via X-ray diffraction (XRD) after 40 days of operation, clearly reveals high anti-fouling property of ATMP as a cathode material. ATMP being a commercial antiscaling agent has inherent chelation properties to stop chemical fouling and thus helped in demonstrating stable long term performance of cathode in the MFCs. NDCP along with ATMP could be used for fabrication of a cost effective fouling resistant cathode for long term use by increasing ORR in MFCs to achieve stable power generation by minimizing scale formation on cathode and effective wastewater treatment simultaneously.

“…This kind of three-dimensionally structured electrode possesses a distinct macroporous network structure with continuously through macropores and high specific surface area: connectivity of macropores can provide the convenience for liquid flowing, thus benefits the fast mass transport; high specific surface area can increase the loading capacity per unit area, provides more sites for the adhesion and growth of microbial, and thus becomes To investigate the effect of SnO 2 on the extracellular electron transfer of the electrochemically active biofilm, cyclic voltammetry was performed. The resistance in the high frequency intercept of real axis can be attributed to ohmic resistance, and it results from the wire connection to external circuit, the electrolyte and the intrinsic resistance of active materials 29 . 3b shows cyclic voltammograms obtained for CNT and CNT-SnO 2 anodes without and with biofilms.…”

A facile electrophoretic deposition method was used to prepare three-dimensional macroporous CNT-SnO 2 monolith as the MFC anode. This 3D CNT-SnO 2 composite presents a clear micro-structure of CNT inside and amorphous SnO 2 nanoparticles coating around the CNT surface, and has an integration of electricity generation and energy storage in MFCs. Experimental results show that CNT-SnO 2 composite possesses good biocompatibility and improved electrical conductivity. Compared with CNT, CNT-SnO 2 presents a much higher output current density (2.21 versus 0.47 mA cm -2 ), power density (673.5 versus 443.1 mW m -2 ). The dischrge-charge experiments show that CNT-SnO 2 composite has a greater specific capacitance than CNT electorde 2 (382 versus 42.8 mF cm -2 ) with a discharge-charge current density of 1 mA cm -2 .These results reveal that 3D CNT-SnO 2 composite has a great promise as the anode material for MFCs. Graphical Abstract3D macroporous CNT-SnO 2 composite as the anode in microbial fuel cells possesses the feature of an integration of electricity generation and energy storage.
