“…The maximum power density obtained using the investigated membranes was in the following order: GO-modified membrane > Nafion > MWCNTsmodified membrane. However, the fresh nanomaterial-modified ceramic membranes showed less ion conductivity and higher oxygen cross-over than the Nafion (Ahilan et al, 2019). Nevertheless, it should be emphasized that the ion conductivity of the modified membrane might be sustained throughout time, whereas that of Nafion's is likely to diminish due to biofouling.…”

Materials at the nanoscale show exciting and different properties. In this review, the applications of nanomaterials for modifying the main components of microbial fuel cell (MFC) systems (i.e., electrodes and membranes) and their effect on cell performance are reviewed and critically discussed. Carbon and metal-based nanoparticles and conductive polymers could contribute to the growth of thick anodic and cathodic microbial biofilms, leading to enhanced electron transfer between the electrodes and the biofilm. Extending active surface area, increasing conductivity, and biocompatibility are among the significant attributes of promising nanomaterials used in MFC modifications. The application of nanomaterials in fabricating cathode catalysts (catalyzing oxygen reduction reaction) is also reviewed herein. Among the various nanocatalysts used on the cathode side, metal-based nanocatalysts such as metal oxides and metal-organic frameworks (MOFs) are regarded as inexpensive and high-performance alternatives to the conventionally used high-cost Pt. In addition, polymeric membranes modified with hydrophilic and antibacterial nanoparticles could lead to higher proton conductivity and mitigated biofouling compared to the conventionally used and expensive Nafion. These improvements could lead to more promising cell performance in power generation, wastewater treatment, and nanobiosensing. Future research efforts should also take into account decreasing the production cost of the nanomaterials and the environmental safety aspects of these compounds.

“…267 According to Pasternak et al, 286 ceramic membranes with higher silica (SiO 2 ) concentrations demonstrated better power output. Ahilan et al 287 synthesized proton-conducting porous ceramic membranes via a polymer-derived ceramic route, which were then investigated in a microbial fuel cell. As filler materials, carbon allotropes including graphene oxide (GO) and MWCNTs were added to their chemical compositions.…”

Increasing populations and urbanization put a lot of pressure on freshwater supplies and use. The increased demand for drinking water can be met by using seawater as a source of freshwater. Desalination and wastewater treatment have been energy-and time-consuming processes in recent years. Microbial desalination cells (MDCs) have gained considerable attention as an emerging technology because of their ability to treat wastewater, desalinate seawater, and produce electricity and value-added products. The efficiency and performance of this technology are affected by numerous factors. In this study, the effect of membranes on the efficiency and performance of this technology is examined. Anionic and cationic, carbon nanotube (CNT), bipolar and osmotic membranes were investigated. Anionic and cationic membranes, as well as their modifications, significantly influence microbial desalination cells.CNT-based membranes have shown significant improvements in water permeability, desalination capacity, strength, anti-fouling, and energy efficiency compared to other membranes. Bipolar membranes prevent the pH of the anode chamber from decreasing, which is essential for MDC operation. The use of FO membranes in microbial desalination cells still faces challenges; for instance, fouling is more likely in FO membranes than ion-exchange membranes, resulting in higher internal resistance and decreased water flux. MDC technology will require research into membrane fouling, electron transfer kinetics, material feasibility, microbial growth, and catalyst durability to be scaled and sustainable. As part of the feasibility study, the performance and stability of the reactor must also be examined.

“…to the coarse pore filter can further raise the proton transfer capacity and selectivity as well as mechanical durability, and inhibit biofouling that always occurs during long‐term operation. [ 165 ] Poly[2,5‐benzimidazole] was utilized as functional conductive material to enhance proton transfer capability of fabric‐based separator, and results showed that a considerable power output (766 mW m −3 ) was achieved in MFCs. [ 166 ] However, the coarse pore filters still face the weakness of high oxygen crossover, severe water penetration and comparatively lower power output.…”

Microbial fuel cells (MFCs), as a sustainable and promising technology to solve both environmental pollution and energy shortage, have captured tremendous attention. The conversion efficiency of chemical energy contained in organic waste or wastewater to electricity via microbial metabolism strongly depends on the performance of each functional unit, including the anode, cathode and separator/membrane used in MFCs. Therefore, significant attention has been paid toward developing advanced functional materials to enhance the performance of each unit or provide new featured functions. This review paper provides a comprehensive review on recent achievements and advances in the modification and development of functional materials for MFC systems, including 1) the development of functional anode materials for enhanced microbial compatibilities as well as electron transfer capabilities, 2) the development of cost‐effective separators/membranes such as ion exchange membrane, porous membrane, polymer electrolyte membrane and composite membrane, and 3) the development of functional cathode catalysts to decrease the over‐potential and enhance the electrocatalytic efficiency for oxygen reduction reaction in order to substitute the common costly Pt catalyst. The challenges and outlooks of functional materials for MFC applications are also discussed.
