Structure evolution of air cathodes and their application in electrochemical sensor development and wastewater treatment

Carbonaceous Anodes and Compatible Exoelectrogens in High-Performance Microbial Fuel Cells: A Review

“…Therefore, when preparing the cathode, in order to simplify the configuration and achieve rapid substrate replacement, the cathode should preferably be able to load proton exchange membranes to construct single chamber cells. 55,56 Finally, in order to improve the binding between electrons and electron acceptors on the cathode, it is usually necessary to load catalysts such as platinum carbon powder, and the cathode materials also need to have corrosion resistance and stability. 57 Since in a MFC the volatile substrates are adsorbed on the anode, it is necessary to improve the corrosion resistance of anode materials.…”

“…In order to improve the Coulombic efficiency of MFCs and achieve efficient substrate degradation by only transferring electrons through external circuits, the cathode should be capable of providing a sufficient site for electron and electron acceptor binding, while also isolating the cation in the MFC chamber from the cathode. Therefore, when preparing the cathode, in order to simplify the configuration and achieve rapid substrate replacement, the cathode should preferably be able to load proton exchange membranes to construct single chamber cells. , Finally, in order to improve the binding between electrons and electron acceptors on the cathode, it is usually necessary to load catalysts such as platinum carbon powder, and the cathode materials also need to have corrosion resistance and stability .

An Overview of Microbial Fuel Cell Technology for Sustainable Electricity Production

“…Comparing the type of configuration of MFC technologies, it is not easy to say that one system is more effective than another if it presents a high efficiency rate. For example, the SC-MFCs based on an air-cathode configuration play a significant role in the implementation and performance of MFCs, considering different advantages such as robustness, low cost, simplicity in terms of structure and use, and low/less internal resistance (which makes them more efficient electrochemically), as has been previously reviewed [42,62]. However, despite the significant advantages of air-cathode SC-MFCs, they also present many disadvantages, such as the formation of precipitates on the cathode surface and the evaporation of water [53], high price (depending on the material used, e.g., Pt), large-scale application limitations, and biofouling issues over time [63].…”

The Efficiency of a Biological Reactor in a Domestic Wastewater Treatment Plant Operating Based on ABS (Acrylonitrile Butadiene Styrene) Material and Recycled PUR (Polyurethane) Foam

“…A pragmatic shift marked a transformation in waste material management and wastewater treatment technology, responding to the substantial global waste production and the demand for economical adsorbents to reduce wastewater treatment costs [4]. Today, a new approach encompasses the integration of waste materials into wastewater treatment and the creation of value-added products from previously used waste adsorbents, including electric material and cementitious materials, ultimately enhancing both waste management efficiency and commercial viability [5][6][7]. Wastewater is generated from various sources, including industrial processes, agricultural activities, and domestic usage [8,9].…”
