“…For BES anodes, carbon has always been the material of choice, because it is not only biocompatible and chemically stable, but can also be produced at comparatively low costs from biological and chemical polymer precursors via carbonisation (pyrolysis). Thus, the pyrolysis of cellulose‐ and lignocellulose‐containing plant materials, like the stem of the kenaf plant ( Hibiscus cannabinus ), coconut shells, or loofah (a tropical cucumber), yields promising carbonaceous electrode materials. In addition, technical cellulose (pulp) products like corrugated cardboard have been shown to provide an excellent basis for electrode materials …”

In this publication, we propose metal-polymer hybrid materials as a novel platform for the development of 3 D anode materials for bioelectrochemical systems, such as microbial fuel cells. Extremely low gravimetric density, high porosity, high electric conductivity, and distinct elastic properties are characteristics that are superior for bioelectrochemical applications. As a proof of concept, we investigated copper-melamine foams (Cu-MF) based on a commercially available, open cell melamine foam. With a low amount of copper (16.3 mg cm for Cu-MF ) used for metallization, such electrode material can be manufactured at low price. The Cu-MF sponges are readily colonized by electrochemically active bacteria and are electrochemically stable over an experimental period of more than 75 days. The Cu-MF-biofilm electrodes exhibit volumetric current densities of up to 15.5 mA cm . During long-term operation, overgrowth of the Cu-MF pore structures by the Geobacter-dominated biofilms occurs, from which demands for future electrode developments are derived.

Seawater might serve as a fresh-water supply for future generations to help meet the growing need for clean drinking water. Desalination and waste management using newer and more energy intensive processes are not viable options in the long term. Thus, an integrated and sustainable strategy is required to accomplish cost-effective desalination via wastewater treatment. A microbial desalination cell (MDC) is a new technology that can treat wastewater, desalinate saltwater, and produce green energy simultaneously. Bio-electrochemical oxidation of wastewater organics creates power using this method. Desalination and the creation of value-added by-products are expected because of this ionic movement. According to assessments, recent investigations on MDC configurations have led to significant changes in their operating characteristics, as well as their design and operational factors. Additionally, the study notes the expanding uses of MDC in bioremediation, nutrient recovery, water softening, and value-added chemical manufacturing. Significant results show that the MDC system produced outstanding desalination without the need for external power, in addition to achieving wastewater treatment and energy recovery without the need for intermediary processes. When it comes to its practical application, some of the technical obstacles include keeping pH stable in cathodic and anodic fluids, increasing internal resistance using catalysts as electrode fillers, along with issues of biofouling and durability. Although MDC technology is currently being developed and scaled up, additional research on membrane fouling avoidance, material feasibility, electron transport kinetics, growth of microorganisms, and catalyst durability is needed.
