Microbial electrochemical systems are intensively discussed as new devices for producing energy or chemicals. In the last years progress in the terms of efficiency and applicability has been achieved. However the potential influence of nanotechnological approaches in the design of such systems with future perspectives of using nanobiosystems as scalable systems have not been addressed. After discussing recent achievements in this field an outlook to the future development of corresponding technology is given, suggesting an interdisciplinary approach.

“…In the process of assembling the single-chamber air-cathode MFCs, a pretreated graphite fiber brush was used as the anode. 15,34,35 The gas diffusion layer (GDL) and the catalyst layer were sequentially rolled onto the stainless steel mesh to form the air cathode. 36,37 Both the (Fe)/Fe 3 O 4 /FeS/NGC-x (x = 600, 700, 800, 900, and 1000) and the commercial Pt/C (10 wt %) were used as the cathode catalysts for MFCs.…”

The critical issues in practical application of microbial fuel cells (MFCs) for wastewater treatment are the high cost and poor activity and durability of precious metal catalysts. To alleviate the activity loss and kinetic barriers for oxygen reduction reaction (ORR) on cathode, (Fe)/FeO/FeS/N-doped graphitic carbon ((Fe)/FeO/FeS/NGC) is prepared as ORR catalyst through a one-step method using waste pomelo skins as carbon source. Various characterization techniques and electrochemical analyses are conducted to illustrate the correlation between structural characteristics and catalytic activity. MFCs with Fe/FeO/FeS/NGC (900 °C) cathode produces the maximum power density of 930 ± 10 mW m (Pt/C of 489 mW m) and maintains a good long-term durability, which only declines 18% after 90 day operation. Coulombic efficiency (22.2%) obtained by Fe/FeO/FeS/NGC (900 °C) cathode is significantly higher than that of Pt/C (17.3%). Metallic state FeS anchored in porous NGC skeleton can boost electron transport through the interconnected channels in spongelike structure to improve catalytic activity. Charge delocalization of C atoms can be strengthened by N atoms incorporation into carbon skeleton, which correspondingly contributes to the O chemisorptions and O-O bond weakening during ORR. Energetically existed active components (Fe and N species) are more efficient than Pt to trap and consume electrons in catalyzing ORR in wastewater containing Pt-poisoning substances (bacterial metabolites). (Fe)/FeO/FeS/NGC catalysts with the advantages of durable power outputs and environmental-friendly raw material can cover the shortages of Pt/C and provide an outlook for further applications of these catalysts.

“…The performance of MFCs is highly dependent on the microbial metabolism, electrode material and reactor design. − Recently, extensive studies have been devoted to accelerate electron transfer in MFCs. One possible solution is to develop efficient anode materials to enhance the interaction between the electrode and bacteria, as the EET between anode and biofilm directly determines the bioelectrochemical processes. − Another possible solution is to facilitate EET from the interior of the bacterial cell out to the electrode.…”

Water-soluble conjugated oligoelectrolyte nanoparticles (COE NPs), consisting of a cage-like polyhedral oligomeric silsesquioxanes (POSS) core equipped at each end with pendant groups (oligo(p-phenylenevinylene) electrolyte, OPVE), have been designed and demonstrated as an efficient strategy in increasing the current generation in Escherichia coli microbial fuel cells (MFCs). The as-prepared COE NPs take advantage of the structure of POSS and the optical properties of the pendant groups, OPVE. Confocal laser scanning microscopy showed strong photoluminescence of the stained cells, indicating spontaneous accumulation of COE NPs within cell membranes. Moreover, the electrochemical performance of the COE NPs is superior to that of an established membrane intercommunicating COE, DSSN+ in increasing current generation, suggesting that these COE NPs thus hold great potential to boost the performance of MFCs.
