Summary: The property of cathode in microbial fuel cell (MFC) is a key factor limiting its output performance. MnO2 nanorods were prepared by hydrothermal method and used as cathode catalysts for MFCs. The unique crystal planes and abundant hydroxyl groups on the surface of MnO2 nanorods provided active adsorption sites, leading to a significantly higher power density and stability compared to other cathode materials.

Summary: This study successfully prepared a series of chalcogen-modified copper and nitrogen co-doped catalysts, which showed improved oxygen reduction reaction (ORR) performance through proper chalcogen doping while maintaining antibacterial properties. Among these catalysts, the optimized Cu2S@Cu-SNC-2 catalyst exhibited excellent durability and ORR activity, outperforming the commercial Pt/C catalyst. The MFC based on Cu2S@Cu-SNC-2 also achieved significantly higher power density and had fewer cathode biofilms.

Summary: In situ electrochemical disinfection using H2O2 via the two-electron molecular oxygen reduction reaction (2e-ORR) is a promising method for sustainable disinfection. However, its effectiveness is limited by the low selectivity and reactivity towards 2e-ORR for H2O2 production. To address this issue, a carbon sphere-modified tubular titanium air diffusion cathode (CS@TTC) was developed to enhance interfacial structures and improve H2O2 production. The CS@TTC cathode showed a 6.59-fold increase in H2O2 accumulation compared to the raw base TTC due to the improved chemical nature of the carbon spheres and superior oxygen mass transfer. Additionally, the disinfection performance of the CS@TTC cathode resulted in a 6.42 log reduction of E. coli after 120 minutes, demonstrating the potential of H2O2-based electrochemical disinfection as a next-generation process.

Summary: Sodium-ion batteries (SIBs) are a low-cost alternative to lithium-ion batteries (LIBs). The use of carbomethoxy-modified insoluble quinone-based disodium salt (Na(2)dmcdbq) improves the ionic diffusion and enhances the rate performance and cycle stability of SIBs. When coupled with carbon nanotubes, Na(2)dmcdbq exhibits a capacity of 180 mAh/g at 4,000 mA/g (22.5C) and retains 151 mAh/g capacity after 6,000 cycles. Pairing with a synthesized P2-type Na0.67Mn0.75Li0.25O2 cathode, the full cell reaches a capacity of 125 mAh/g (0.2C) and runs for 1,000 cycles at 2C.

Summary: The study focused on nano-structuring and functionalizing graphite using plasma treatments and immobilizing laccase as a biocatalyst for enzymatic biofuel cell cathode. The optimized parameters of atmospheric pressure plasma jet treatment led to a four-fold enhancement in oxygen reduction reaction current density on carbon nanowalls. The efficient DET transfer was confirmed by the orientation of oxidized laccase covalently immobilized on the electrode surface.
