“…They argued that the recovered power density after 17 cycles was about 96% of the initial value compared to 60% for the bare cathode. Similarly, Noori et al (2018) also reported that the incorporation of silver in the catalyst layer of the composite helped recover 95% of the initial power density after 90 cycles. Both studies attributed the achievements made to the antibacterial properties of the silver NPs (AgNPs) (Yang et al, 2016;An et al, 2017).…”

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.

“…Pre‐treated carbon cloth having dimension of 5 cm by 5 cm was used as base cathode material. The surface of the carbon cloth was modified with Fe x MnO y /graphite containing ink‐based catalyst solution following a protocol reported in the literature . In brief, 2 mg/cm 2 of Fe x MnO y /graphite (1 mg/cm 2 Fe x MnO y +1 mg/cm 2 graphite powder) catalyst was suspended in 5 ml isopropyl alcohol having 100 μl Nafion 117 binder.…”

Microbial electrosynthesis (MES) can efficiently convert CO2 into valuable chemicals. A biocathode, which plays central role in MES process, is expected to have very high surface area and catalytic activity to derive the cathodic reaction flawlessly. In this study, a highly porous bimetallic FexMnOy (x=1, 2 and y=3, 4) microsphere was synthesized and applied as cathode catalyst in a single chamber MES. MES having FexMnOy exhibited higher net acetate production rate (204 mM/m2d) and coulombic efficiency (58 %) than the MES without catalyst (180 mM/m2d and 34 %). The excellent performance of MES with FexMnOy was attributed to the high Brunauer‐Emmett‐Teller (BET) surface area (around 278 m2/g) with rough surface and efficient electron transfer from cathode to microorganism promoted by FexMnOy complex. The cathode with FexMnOy reduced charge transfer resistance by ∼70 % and enhanced the exchange current density by 7.2‐times compared to plain cathode. This study suggests that FexMnOy can be used as the highly efficient and low‐cost catalyst on cathode of scaled up MESs.

“…Bioelectrochemical systems based on the bacterial metabolic pathways as a model reaction to derive renewable energy from waste resources is demonstrated as a potential solution to global energy shortage ( Noori et al., 2018 , 2019 ; Das et al., 2018 ; Rajesh et al., 2018 ). For example, a microbial fuel cell can generate electricity from organic matters present in waste streams wiring EABs with graphitic or metal electrodes ( Noori and Verma, 2019 ; Reddy et al., 2019 ; Noori et al., 2016 ).…”

Summary Goal of sustainable carbon neutral economy can be achieved by designing an efficient CO 2 reduction system to generate biofuels, in particular, by mimicking the mechanism of natural photosynthesis using semiconducting nanomaterials interfaced with electroactive bacteria (EAB) in a photosynthetic microbial electrosynthesis (PMES) system. This review paper presents an overview of the recent advancements in the biohybrid photoanode and photocathode materials. We discuss the reaction mechanism observed at photoanode and photocathode to enhance our understanding on the solar driven MES. We extend the discussion by showcasing the potential activity of EABs toward high selectivity and production rates for desirable products by manipulating their genomic sequence. Additionally, the critical challenges associated in scaling up the PMES system including the strategies for diminution of reactive oxygen species, low solubility of CO 2 in the typical electrolytes, low selectivity of product species are presented along with the suggestions of alternative strategies to achieve economically viable generation of (bio)commodities.
