The activated bamboo char (ABC) was available commercially and carbon nanofibers (CNF) were grown on its surface by a CVD method. The resultant composites were characterized by nitrogen method at 77K and scanning electron microscopy (SEM). The structure of bamboo-based porous carbon might be tunable by adjusting purposively the growth of CNFs. The CNF/ABC composite would combine the properties ...

Engineering applications of carbon nanofibers and nanotubes require their alignment in specific directions. Single-walled carbon nanotubes can be aligned in a magnetic field due to the presence of small amounts of catalyst elements, such as Ni and Co. However, for carbon nanofibers, their extremely low magnetic susceptibility is not sufficient for magnetically induced alignment. We present a me...

Carbon nanotubes (CNTs)/MnOx-Carbon hybrid nanofibers have been successfully synthesized by the combination of a liquid chemical redox reaction (LCRR) and a subsequent carbonization heat treatment. The nanostructures exhibit a unique one-dimensional core/shell architecture, with one-dimensional CNTs encapsulated inside and a MnOx-carbon composite nanoparticle layer on the outside. The particula...

Catalytically graphitized electrospun carbon nanofibers adorned uniformly with fine nickel nanoparticles were successfully prepared. The procedure was based on the electrospinning technique and the use of nickel precursor to create both graphitized nanofibers and nickel nanoparticles under a relatively low-temperature heat treatment. The X-ray diffraction and Raman results clearly proved cataly...

Epoxy nanocomposites of different content of carbon nanofibers upto 1 wt% have been fabricated under room temperature and refrigerated curing conditions. The composites were studied in terms of mechanical and electrical properties. Flexural modulus and hardness were found to increase significantly in refrigerated samples due to prevention of aggregates of nanofibers during cure condition. Incre...

Nanometer scale carbon fibers (carbon nanofibers) are of great interest to scientists and engineers in fields such as materials science, composite production, and energy storage due to their unique chemical, physical, and mechanical properties. Precursors currently used for production of carbon nanofibers are primarily from nonrenewable resources. Lignin is a renewable natural polymer existing ...

Novel carbon-coated MoO(2) nanofibers have been fabricated through a controlled route based on single-nozzle electrospinning, air stabilization, and reduction/carbonization processes. They are composed of both a uniform carbonaceous shell of ∼3 nm in thickness and a hierarchical core made of primary MoO(2) nanocrystal clusters of ∼20 nm in size. Importantly, the electrode made of such unique ca...

Boron, nitrogen dual-doping 3D hard carbon nanofibers thin film is synthesized using a facile process. The nanofibers exhibit high specific capacity and remarkable high-rate capability due to the synergistic effect of 3D porous structure, large surface area, and enlarged carbon layer spacing, and the B, N codoping-induced defects.

Single layers of WS2 nanoplates are uniformly embedded in nitrogen-doped carbon nanofibers (WS2@NCNFs) via a facile electrospinning method. Crystallization of the single-layered WS2 nanoplates and in situ nitrogen doping into the carbon nanofibers were simultaneously accomplished during a two-step heat treatment. The distinctive structure of the WS2@NCNFs enables outstanding electrochemical per...

Much of the excitement surrounding new carbon nanomaterials can be traced to their directional properties, which arise through precise orientation of graphene layers that are the anisotropic building blocks of all sp-hybridized carbon forms. The high conductivity, strength, and stiffness of carbon nanotubes are directly related to the parallel orientation of graphene layers relative to the tube...
