“…During the whole stage, NC@CMF could drive more flavin excretion than the control groups. In general, flavin can transfer electrons to the anode through remote diffusion, thus the increase in flavin content can promote the EET process in bacteria [51]. After inoculation for a certain time, mature biofilms were grown on the anodes.…”

Microbial fuel cell (MFC) performance is affected by the metabolic activity of bacteria and the extracellular electron transfer (EET) process. The deficiency of nanostructures on macroporous anode obstructs the enrichment of exoelectrogens and the EET. Herein, a N-doped carbon nanowire-modified macroporous carbon foam was prepared and served as an anode in MFCs. The anode has a hierarchical porous structure, which can solve the problem of biofilm blockage, ensure mass transport, favor exoelectrogen enrichment, and enhance the metabolic activity of bacteria. The microscopic morphology, spectroscopy, and electrochemical characterization of the anode confirm that carbon nanowires can penetrate biofilm, decrease charge resistance, and enhance long-distance electron transfer efficiency. In addition, pyrrolic N can effectively reduce the binding energy and electron transfer distance of bacterial outer membrane hemin. With this hierarchical anode, a maximum power density of 5.32 W/m3 was obtained, about 2.5-fold that of bare carbon cloth. The one-dimensional nanomaterial-modified macroporous anodes in this study are a promising strategy to improve the exoelectrogen enrichment and EET for MFCs.

Microbial fuel cells (MFCs) are sustainable energy technologies that could resolve pollution challenges brought by various activities. It can meet energy demand by producing bioelectricity through catabolizing organic matter. Over the past two decades, research on many microbes have been used in MFCs, which intrigued researchers to explore the underlying electron transfer mechanism between microbe and anode. Electron transfer between electrode and microorganism occurs via different pathways: direct, indirect electron transfer and interspecies electron transfer. Shewanella and Geobacter are well‐known for microbe–electrode and microbe–microbe electron transfer. This review provides an overview of the significant varieties of microbes utilized in MFCs for simultaneous bioelectricity generation and wastewater treatment. Mechanisms of different modes of electron transfer involved during the oxidation of organic wastes in the anode section of MFCs are highlighted. Furthermore, this review also details some of the techniques to promote extracellular electron transfer efficiency which is important for the enhanced performance of MFC in terms of power, current generation and wastewater remediation. A perspective of challenges to be addressed for the effective functioning of these technologies, opportunities for MFC systems to be scaled up and associated techno‐economic analysis are discussed. © 2024 Society of Chemical Industry (SCI).
