Mesoporous carbon nanofibers with large cage-like pores activated by tin dioxide and their use in supercapacitor and catalyst support

Microstructure and photocatalytic activity of electrospun carbon nanofibers decorated by TiO 2 nanoparticles from hydrothermal reaction/blended spinning

“…The preparation process of rough PAN fibers could be seen in nanoparticles changed from large to small with further elevating heat treatment temperature. These morphological changes might be mainly caused by the influence of heat treatment temperature on the TiO 2 crystals [34]. In the blended spinning pathway, as could be seen, BCNFs had a much smoother surface in comparison with HCNFs.…”

Graphitic carbon nitride nanosheet-assisted preparation of N-enriched mesoporous carbon nanofibers with improved capacitive performance

“…Benefiting from the advantage of a flexible and conductive network for electron transfer with a short path, porous carbon nanofibers (CNFs) have attracted tremendous attention for their potential application in electrochemical energy storage as electrode materials for supercapacitors (SCs) with a fast charging capability and long life span [1][2][3][4][5][6][7][8]. As such, to meet the ever-increasing requirements for high-efficiency energy storage devices in modern society, it is important to synthesis CNFs with both the desired pore structure and functionalized groups to improve the performance of CNF-based SCs to have a high energy density and good rate capability.…”

“…So far, MCNFs have been widely prepared through the template technique by using sacrificial templates like anodized aluminum oxide (AAO) [13], SiO 2 [12], Sn [2], and ZnO nanoparticles [18]. Nevertheless, in these cases, one still needs to remove these inorganic templates by corrosive acids or alkalis, which is laborious and industrially undesirable because of the high cost and long time required.…”

Carbon nanofiber/graphene composite paper for flexible supercapacitors with high volumetric capacitance

“…Although considerable efforts, such as improving conductivity or specific surface area [4], have been made to improve gravimetric capacitance of the electrode materials, the volumetric capacitance, more important in practical application [5], is very low as a consequence of low bulk density of traditional electrospinning nanofiber paper. Hence, it is of great significance to increase the bulk density of electrospun carbon nanofiber-based electrodes without sacrificing free-standing nature and flexibility.…”
