“…Despite all this progress, unmodified graphene derivative materials are not preferable due to their toxic effects on bacteria. On the other hand, unmodified metal derivatives also suffer from corrosion issues in MFCs [11,12]. Therefore, graphene derivatives with metal/metal oxide nanoparticles or conductive polymer-based composite materials are used as anodes to enhance the working efficiency of MFCs.…”

The recycling and treatment of wastewater using microbial fuel cells (MFCs) has been attracting significant attention as a way to control energy crises and water pollution simultaneously. Despite all efforts, MFCs are unable to produce high energy or efficiently treat pollutants due to several issues, one being the anode’s material. The anode is one of the most important parts of an MFC. Recently, different types of anode materials have been developed to improve the removal rate of pollutants and the efficiency of energy production. In MFCs, carbon-based materials have been employed as the most commonly preferred anode material. An extensive range of potentials are presently available for use in the fabrication of anode materials and can considerably minimize the current challenges, such as the need for high quality materials and their costs. The fabrication of an anode using biomass waste is an ideal approach to address the present issues and increase the working efficiency of MFCs. Furthermore, the current challenges and future perspectives of anode materials are briefly discussed.

In this study, thin-film composite with embedded polyester screen, cellulose triacetate with a cast nonwoven and cellulose triacetate with embedded polyester screen (CTA-ES) were examined as the intermediate membranes in osmotic microbial fuel cells (OsMFCs). The reactors were fed with actual landfill leachate and the performance was studied in two operation modes: active layer facing draw solution and active layer facing feed solution (AL-FS). The OsMFC with CTA-ES exhibited the best energy generation (maximum power density: 0.44 W m-2) and pollutant removal efficiency (ammonia nitrogen: 70.12 ± 0.28%, total nitrogen: 74.04 ± 0.33%) in the AL-FS mode, which could be ascribed to the lowest internal resistance (236.75 ohm) and highest microbial richness. Pseudomonas was the highest proportion of microbial in OsMFCs. The results of this study has demonstrated the potential of OsMFCs for landfill leachate treatment.

“…To avoid this drawback, a lot of studies were therefore focused on using pure sugary organics, such as xylose, starch [18][19][20] and so on, as predecessor material for preparation of activated carbon. However, the extract of sugary organic from biomass would increase the cost, more and more researches had been turned to study the direct use of natural resources for carbonaceous material preparation [21][22][23][24]. To lower the fabrication cost and avoid potential adverse environmental impact, great efforts have been devoted to the synthesis of carbonaceous materials from biomass in a sustainable approach, for example, under low temperature with sulfuric acid as the catalyst [15,23].…”

In microbial fuel cells (MFCs), an important factor limiting practical applications is the high catalyst cost in cathode. Herein a rice husk-based porous carbon made through hydrolysis, activation and rolling was used as novel cathode. These porous carbons were characterized by SEM, XPS and BET analysis, and electrochemical measurements including linear sweep voltammetry and Tafel test were investigated. A maximum powder density (317.7 � 0.4 mW m À 2) on AC-KOH-1h with the largest BET surface area of 1809 m 2 g À 1 was obtained. This study revealed a fresh territory about the application of porous carbon produced by renewable resources for MFC electrode.
