TaC Nanowire/Activated Carbon Microfiber Hybrid Structures from Bamboo Fibers

Abstract

Hybrid structures consisting of TaC nanowires and activated carbon microfibers are synthesized via a carbothermal method using bamboo fibers as both the carbon source and the template. The nanowires exhibit a Young's modulus of 364.7 GPa and low electrical resistivity of 63.6 μΩ·cm. These unique hierarchical heterostructures of TaC/C demonstrate remarkable energy storage capabilities as a new promising material for high performance supercapacitors.

Biotemplating fabrication, mechanical and electrical characterizations of NbC nanowire arrays from the bamboo substrate

“…6b shows the equivalent circuit of this technique, where R NW-P , R NW , R S-NW , and R S represent the contact resistance of the probe to the nanostructure, the resistance of the nanostructure, the contact resistance of the sample holder to the nanostructure, and the resistance of the sample holder, respectively. The resistance of the sample can be calculated by R NW = R NW-TIP À R NW-ROOT = (R S + R S-NW + R NW-P + R NW-TIP ) À (R S + R S-NW + R NW-P + R NW-ROOT ) [13]. Fig.…”

“…6 shows the in situ characterization of individual NbC nanowires in TEM. A multipoint technique [13] (Fig. 6a) was used for the in situ electrical property characterization of individual nanostructures inside TEM with a nanomanipulator.…”

“…To date, various techniques including carbon nanotube confined reaction [18], chemical vapor deposition [19], carbon thermal reduction [20][21][22], and pyrolysis of polymeric precursors [23] have been developed for the preparation of 1D carbide nanostructures. In our recent studies, a facile and cost-effective biotemplating method has been developed to synthesize 1D TMC nanostructures [13,14,24].…”

“…In the past decades, one-dimensional (1D) TMC nanostructures such as nanowires [13] and nanorods [14] have drawn extensive attention because of their size-dependent optical, electronic [13][14][15], mechanical [13,14,16], and field emission properties [17], opening up unprecedented opportunities for constructing nano-devices with new functionalities. However, there are only few routes for synthesizing 1D NbC nanostructures.…”

Solid oxide membrane-assisted controllable electrolytic fabrication of metal carbides in molten salt

“…particular, nanostructured MCs materials hold promise for various applications due to their interesting properties. [12][13][14][15][16][17][18][19] While the high melting points of MCs are useful for high-temperature applications, they also cause problems when preparing these MCs materials. 6 In addition, MCs ceramics such as tantalum carbide (TaC) and zirconium carbide (ZrC) generally possess high melting points and thus have the potential to be used for extremely high-temperature applications.…”
