“…In most cases, hierarchical structures used to form microbial anodes are based on the association of a macro-porous structure, which corresponds to the types of structure dealt with in this review, and a nano-structure, which can be obtained in various ways, including by using carbon nanotubes (Zhao et al, 2011;Flexer et al 2013) or nano-porous graphene (Qiao et al, 2014). These nano-structures can promote bacterial attachment and extracellular electron transfer (Flexer et al, 2013;Yuan et al, 2019), offer a large active area for mediator reduction (Wu et al, 2018), and even promote microbial growth with great excretion of electron mediators (Zou et al, 2017) but, at the level of microbial cells, they should be considered as surface functionalization (Zou et al 2017;Yuan et al, 2019) or surface structuring (Zou et al, 2017) rather than porosity. Hierarchical porous structures are promising electrode architectures, at the crossroads of cell-level porosity and nano-structured surfaces.…”

Microbial anodes are the cornerstone of most electro-microbial processes. Designing 3-dimensional porous electrodes to increase the surface area of the electroactive biofilm they support is a key challenge in order to boost their performance. In this context, the critical review presented here aims to assess whether an optimal range of pore size may exist for the design of microbial anodes. Pore sizes of a few micrometres can enable microbial cells to penetrate but in conditions that do not favour efficient development of electroactive biofilms. Pores of a few tens of micrometres are subject to clogging. Sizes of a few hundreds of micrometres allow penetration of the biofilm inside the structure, but its development is limited by internal acidification. Consequently, pore sizes of a millimetre or so appear to be the most suitable. In addition, a simple theoretical approach is described to establish basis for porous microbial anode design.

“…Figure 2 demonstrates the advantages and disadvantages of MFC. Recently, nanotechnology or use of nanomaterial has revolutionized the fabrication of components of MFC to improve the performance and efficacy of traditional MFC in terms of electron conductivity, power density, cost, thermal stability, ORR rate and anti-corrosion [94,95], particularly the modification of electrodes (anode and cathode) by nanomaterials. This is because the materials used in the production of electrodes that are the major constituent of MFC are essential to determine the overall performance of MFC [96].…”

The world energy production trumped by the exhaustive utilization of fossil fuels has highlighted the importance of searching for an alternative energy source that exhibits great potential. Ongoing efforts are being implemented to resolve the challenges regarding the preliminary processes before conversion to bioenergy such as pretreatment, enzymatic hydrolysis and cultivation of biomass. Nanotechnology has the ability to overcome the challenges associated with these biomass sources through their distinctive active sites for various reactions and processes. In this review, the potential of nanotechnology incorporated into these biomasses as an aid or addictive to enhance the efficiency of bioenergy generation has been reviewed. The fundamentals of nanomaterials along with their various bioenergy applications were discussed in-depth. Moreover, the optimization and enhancement of bioenergy production from lignocellulose, microalgae and wastewater using nanomaterials are comprehensively evaluated. The distinctive features of these nanomaterials contributing to better performance of biofuels, biodiesel, enzymes and microbial fuel cells are also critically reviewed. Subsequently, future trends and research needs are highlighted based on the current literature.

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.
