“…Bai et al [143] created polyvinyl chloride nanofibers by electrospinning and carbonization to form a thousand-layer cake structure, which was beneficial to electrolyte penetration and the rapid diffusion of Na + . Cai et al [144] prepared a new carboxylated multiwall carbon nanotube/carbon microbial fuel nanofiber-composite electrode using electrospinning technology. The interconnected and mechanical properties of the fibers were improved, and contact resistance was reduced by thermocompression.…”

Electrospinning has gained constant enthusiasm and wide interest as a novel sustainable material processing technique due to its ease of operation and wide adaptability for fabricating eco-friendly fibers on a nanoscale. In addition, the device working parameters, spinning solution properties, and the environmental factors can have a significant effect on the fibers’ morphology during electrospinning. This review summarizes the newly developed principles and influence factors for electrospinning technology in the past five years, including these factors’ interactions with the electrospinning mechanism as well as its most recent applications of electrospun natural or sustainable composite materials in biology, environmental protection, energy, and food packaging materials.

Microbial fuel cells (MFCs) exhibit great potential to generate power through organic wastewater treatment. Limitations have restricted the advanced development of MFCs, including low power density, expensive electrode materials, and the challenge to manufacture MFCs in large scale. However, the introduction of advanced anode materials, especially porous and nanostructured materials, is believed to be an effective way to solve the problems, as they can promote bacteria extracellular electron transfer (EET) because of their unique physical, chemical, and electrical properties. Nanostructured materials, including carbon nanotubes (CNTs), graphene, activated carbon fiber, metal, metal oxides and conductive polymers, show many appreciable properties such as good conductivity, large specific surface area, and excellent catalytic activity. Additionally, nanomaterials with unique electrochemical properties provide strong charge interactions with organic compounds and the direct electrochemistry process between bacteria and the anode. This Review comprehensively focuses on the recent development of modification of nanostructured anode materials in view of crucial intrinsic factors to enhance electricity output. Furthermore, the enhanced performance of MFCs and the corresponding known mechanism is also discussed, which enables active bacteria to facilitate electron transfer. Finally, promising strategies to modify anode nanomaterials for future research are presented.

“…Nanoparticle modified nanofibers have been successfully applied in divergent areas such as catalysis [1][2][3], tissue engineering [4], photochemical applications [5][6][7], capacitors [8], energy applications [9], membrane electrodes in fuel cells [10], etc... Fuel cells (FC) are environmentally friendly alternative power sources [11] and until now from solid oxide to microbial FCs various studies have been reported which use the advantage of electrospun polymers [10,[12][13][14][15]. Electrospun polymers exhibit unique electrochemical activity.…”

Electrocatalytic effect of the untreated and TiO 2 +polyacrylonitrile (PAN) modified discarded battery coal (DBC) and pencil graphite electrodes (PGE) were evaluated in fuel cell (FC) applications. TiO 2 +PAN solution is coated on PGE and DBC electrodes by electrospinning. According to the FESEM and EDS characterizations, TiO 2 and PAN nanofibers are found to be approximately 40 and 240 nm sized. TiO 2 +PAN/PGE showed the best FC performances with 2.00 A cm-2 current density and 5.05 W cm-2 power density values, whereas TiO 2 +PAN/DBC showed 0.68 A cm-2 current density and 0.62 W cm-2 power density values. Electrochemical characterizations of PGE and TiO 2 +PAN/PGE electrodes were investigated by cyclic voltammetry and electrochemical impedance spectroscopy. Finally, long-term FC 2 measurement results of developed electrodes exhibited very reasonable recovery values. Along with the comparison of the electrode performances, the recovery of DBCs as electrodes for renewable energy production has been achieved.
