To mitigate the adverse effects of binders in the anode of microbial fuel cells (MFCs) and to enhance the performance of WO3 anodes, the WO3-X/CC, serving as a high-performance anode for MFCs, was developed using magnetron sputtering to apply tungsten oxide onto carbon cloth. The WO3-X/CC anode significantly reduces the charge transfer resistance (Rct) to 9.05 Ω, compared to 43.12 Ω for CC anode. The designed anode also enhances electron transport and extracellular electron transfer (EET), reaching a peak power density of 2644 mW m-2, which is 1.67 times greater than that of uncoated CC (1586 mW m-2). Additionally, it demonstrates good wettability and microbial adhesion, which increases the population of electrogenic bacteria Geobacter to 79% on the electrode. These results demonstrate the potential of MFC constructed with oxygen-vacancy-rich WO3-X/CC anodes for wastewater treatment.
Microbial fuel cells (MFCs) enable simultaneous energy generation and organic waste treatment; however, their performance is often limited by inefficient electron transfer at the microbe–electrode interface. Carbon nanotubes (CNTs) have been widely investigated as anode materials owing to their high electrical cond...

Microbial fuel cells (MFCs) offer simultaneous wastewater treatment and electricity generation, but their practical performance is limited by inefficient extracellular electron transfer (EET) and interfacial losses at the electrode–biofilm interface. Conductive polymers (CPs), particularly polyaniline (PANI), polypyrro...

Fiber-shaped zinc-ion batteries are highly deformable and can store energy in irregular spaces. Fiber cathodes with carbon fiber cores can be continuously prepared via wet spinning. In this work, MXene is introduced into the cathode by directly hybridizing with vanadium oxide, acting as a bridge to enhance the interfac...
