“…(CNTs/PANI) 12 /APTES/ITO electrode displays outstanding electrochemical performance with the maximal current density of 7.03 ± 1.6 µA/cm 2 , which is 26 times higher than that on the plain ITO electrode. This result is also higher than the previously reported 3.80 µA/cm 2 on nanograss array boron doped diamond electrode (BDD) [37,38], 2.93 µA/cm 2 on (Au/PAH) 6 /BDD electrode [39] and ~1.3 µA/cm 2 on (PAH/PSS) 4 /(PAH/Fe 2 O 3 ) 2 /PAH/ITO electrode [40]. Remarkably, the current density is also higher than that on the superhydrophilic ITO electrodes with or without the addition of riboflavin as a mediator [30].…”

Microbial fuel cells (MFCs) are promising devices for sustainable energy production, wastewater treatment and biosensors. Anode materials directly interact with electricigens and accept electrons between cells, playing an important role in determining the performance of MFCs. In this study, a novel carbon nanotubes (CNTs) and polyaniline (PANI) nanocomposite film modified Indium-tin oxide (ITO) anode was fabricated through graft polymerization of PANI after the modification of γ-aminopropyltriethoxysilane (APTES) on ITO substrate, which was followed by layer-by-layer (LBL) self-assembling of CNTs and PANI alternatively on its surface. (CNTs/PANI) n /APTES/ITO electrode with low charge transfer resistance showed better electrochemical behavior compared to the bare ITO electrode. Twelve layers of CNTs/PANI decorated ITO electrode with an optimal nanoporous network exhibited superior biocatalytic properties with a maximal current density of 6.98 µA/cm 2 , which is 26-fold higher than that of conventional ITO electrode in Shewanella loihica PV-4 bioelectrochemical system. MFCs with (CNTs/PANI) 12 /APTES/ITO as the anode harvested a maximum output power density of 34.51 mW/m 2 , which is 7.5-fold higher than that of the unmodified ITO electrode. These results demonstrate that (CNTs/PANI) 12/ APTES/ITO electrode has superior electrochemical and electrocatalytic properties compared to the bare ITO electrode, while the cellular toxicity of CNTs has an effect on the performance of MFC with (CNTs/PANI) n /APTES/ITO electrode.

“…d and 3e). This possibility is unsurprising, since electrochemically active microorganisms naturally transfer electrons in their anaerobic habitat to the frequently occurring iron oxides hematite ( α ‐Fe 2 O 3 ) , , , goethite (FeO(OH)), or magnetite (Fe 3 O 4 ) . Adding hematite nanocolloids to Shewanella loihica PV‐4 induces the formation of electrically conductive networks and thereby improves the EET .…”

Strategies for the Targeted Improvement of Anodic Electron Transfer in Microbial Fuel Cells

The concept of the microbial fuel cell (MFC) has existed for over 100 years, but only within the last decade, the practical implementation has become conceivable due to microbial and technical progress. This review article presents available strategies to increase the limiting extracellular electron transfer (EET) in the anode space of MFCs. Therefore, organism‐based improvements as well as the effects of (bio–)polymers and redox mediators on ETT will be demonstrated.

“…d und e). Dies ist nicht weiter überraschend, da elektrochemisch aktive Mikroorganismen in ihrem natürlichen anaeroben Habitat beim Abbau organischer Substanzen Elektronen u. a. auf die sehr häufig vorkommenden Eisenoxide Hämatit (αFe 2 O 3 ) , , , Goethit (FeO(OH)) oder Magnetit (Fe 3 O 4 ) übertragen. So zeigte sich, dass die Zugabe von Hämatit‐Nanokolloiden bei Shewanella loihica PV‐4 die Bildung elektrisch leitender Netzwerke induziert und damit der EET verbessert wird .…”

Das Konzept der mikrobiellen Brennstoffzelle (microbial fuel cell, MFC) existiert seit über 100 Jahren, doch erst im letzten Jahrzehnt ist deren praktische Anwendung in der Abwasseraufbereitung auch in Maßstäben bis 1000 L realisiert worden. In diesem Beitrag werden verfügbare Strategien vorgestellt, um den bislang noch limitierenden extrazellulären Elektronentransfer (EET) im Anodenraum von MFCs zu erhöhen. Dafür werden Organismen-basierte Ansätze sowie der Einfluss von (Bio-)Polymeren und Redox-Mediatoren auf den EET vorgestellt.The concept of the microbial fuel cell (MFC) has existed for over 100 years, but only since the last decade its practical implementation in waste water treatment has been realized in scales up to 1000 L.

Therefore, organism-based improvements as well as the effect of (bio)polymers and redox mediators on ETT will be demonstrated.
