“…MOFs have several advantages including distinctive skeletons, large specific surface area and tuneable pore structure. 164 Due to the presence of unsaturated metal-ion active sites, MOFs are a great candidate for excellent electrochemical catalysts. 165 Ni-MOF-74 and Ni–N–C (Ni-MOF-74 subjected to pyrolysis treatment at different temperatures) have been employed as air–cathode catalysts in MFCs.…”

“…Platinum-based cathode catalysts can improve the activity of oxygen reduction [ 84 ]. However, they have limited availability in large-scale applications due to high costs and low stability [ 85 ]. Currently, more studies are attempting to develop nanocomposite-based cathode catalysts to enhance the electrochemical activity of MFC systems.…”

The microbial fuel cell has been considered a promising alternative to traditional fossil energy. It has great potential in energy production, waste management, and biomass valorization. However, it has several technical issues, such as low power generation efficiency and operational stability. These issues limit the scale-up and commercialization of MFC systems. This review presents the latest progress in microbial community selection and genetic engineering techniques for enhancing microbial electricity production. The summary of substrate selection covers defined substrates and some inexpensive complex substrates, such as wastewater and lignocellulosic biomass materials. In addition, it also includes electrode modification, electron transfer mediator selection, and optimization of operating conditions. The applications of MFC systems introduced in this review involve wastewater treatment, production of value-added products, and biosensors. This review focuses on the crucial process of microbial fuel cells from preparation to application and provides an outlook for their future development.

“…These produced electrons are transferred to the anode of the MFC via electrically conductive nanowires or mediators or direct transfer from bacterial cells housed on the electrode. These electrons then flow through an external circuit to the cathode, while the protons migrate through the PEM from the anodic chamber to cathodic chamber [92] (Figure 3). Double or single chamber MFCs, either with aqueous cathode or air cathode have been well utilized by researchers for the removal of organic contaminants from wastewater [93].…”

Bioelectrochemical systems (BESs) are a unique group of wastewater remediating technology that possesses the added advantage of valuable recovery with concomitant wastewater treatment. Moreover, due to the application of robust microbial biocatalysts in BESs, effective removal of emerging contaminants (ECs) can be accomplished in these BESs. Thus, this review emphasizes the recent demonstrations pertaining to the removal of complex organic pollutants of emerging concern present in wastewater through BES.Owing to the recalcitrant nature of these pollutants, they are not effectively removed through conventional wastewater treatment systems and thereby are discharged into the environment without proper treatment. Application of BES in terms of ECs removal and degradation mechanism along with valuables that can be recovered are discussed. Moreover, the factors affecting the performance of BES, like biocatalyst, substrate, salinity, and applied potential are also summarized. In addition, the present review also elucidates the occurrence and toxic nature of ECs as well as future recommendations pertaining to the commercialization of this BES technology for the removal of ECs from wastewater. Therefore, the present review intends to aid the researchers in developing more efficient BESs for the removal of ECs from wastewater.
