“…These CNFs can be used for different electrochemical applications just like thermal grown CNTs. A review of growth, properties, and application of CNFs can be found here . After examining the individual properties of VACNFs and 3DG, it can be envisioned that the PECVD growth of VACNF on 3DG is expected to result in an efficient hybrid carbon structure.…”

Graphene and carbon nanotubes/fibers (CNT/CNF) hybrid structures are emerging as frontier materials for high-efficiency electronics, energy storage, thermoelectric, and sensing applications owing to the utilization of extraordinary electrical and physical properties of both nanocarbon materials. Recent advances show a successful improvement in the structure and surface area of layered graphene by incorporating another dimension and structural form-three-dimensional graphene (3DG). In this study, vertically aligned CNFs were grown using plasma enhanced chemical vapor deposition on a relatively new form of compressed 3DG. The latter was synthesized using a conventional thermal chemical vapor deposition. The resulting free-standing hybrid material is in-situ N doped during synthesis by ammonia plasma and is produced in the form of a hybrid paper. Characterization of this material was done using electrochemical and spectroscopic measurements.The N doped hybrid showed relatively higher surface area and improved areal current density in electrochemical measurements than compressed pristine 3DG, which makes it a potential candidate for use as an electrode material for supercapacitors, sensors, and electrochemical batteries.

“…CNFs are one of the most important members of carbon fibers that are usually useful in many applications due to their unique mechanical, physical, chemical, and electrical [ 1 , 2 ] properties, and they also have fibrous, cylindrical, and cup-stacked structures that can produce a nano-scaled quantum effect [ 3 ]. CNFs are carbon allotropes with a diameter of around 50–100 nm and a length of between one and a hundred micrometers [ 4 ].…”

“…The rubber fruit comprises three major components: the fruit shell, the seed shell, and the seed itself, with the fruit shell accounting for 70% of the total weight, 9% of the seed shell, and 21% of the seed [ 35 ]. Rubber plantations produce approximately 1000 kg of rubber fruit per hectare per year [ 4 ], equating to approximately 3.6 million tons of rubber fruit per year. Therefore, raw materials will be available in the form of rubber fruit shells (RFS) of 2.569 million tons per year, rubber seed shells (RSS) of 0.330 million tons per year, and rubber seeds (RS) of 0.771 million tons per year.…”

Recently, the conversion of biomass into carbon nanofibers has been extensively studied. In this study, carbon nanofibers (CNFs) were prepared from rubber fruit shell (RFS) by chemical activation with H3PO4, followed by a simple hydrothermal process at low temperature and without a vacuum and gas catalyst. XRD and Raman studies show that the structure formed is an amorphous graphite formation. From the thermal analysis, it is shown that CNFs have a high thermal stability. Furthermore, an SEM/TEM analysis showed that CNFs’ morphology varied in size and thickness. The obtained results reveal that by converting RFS into an amorphous carbon through chemical activation and hydrothermal processes, RFS is considered a potential biomass source material to produce carbon nanofibers.

“…The use of carbon nanofibers (CNFs) is being expanded to improve the performance of industrial products, such as batteries, supercapacitors, solar cells, sensors, catalysts, and adsorbents, because CNFs have excellent electrical, thermal, mechanical, and physicochemical properties resulting from their unique carbon nanostructure and morphologies (Desmaris et al 2015;Feng et al 2014;Jiang 2014;Peng et al 2016;Song and Shen 2014;Zhang et al 2014Zhang et al , 2016. Recently, the biocompatibility of CNFs has attracted attention, and the biomedical applications of CNFs [e.g., bone regeneration, biosensors, and antibiotic materials (Ashfaq et al 2016;Erdem et al 2015;Gao et al 2016;Stout 2015;Zhang et al 2014)] have increased.…”

Low-temperature growth of nitrogen-doped carbon nanofibers by acetonitrile catalytic CVD using Ni-based catalysts

et al. 2016

To synthesize nitrogen-doped carbon nanofibers (N-CNFs) at high growth rates and low temperatures less than 673 K, nickel species (metallic nickel and nickel oxide) supported on alumina particles were used as the catalysts for an acetonitrile catalytic chemical vapor deposition (CVD) process. The nickel:alumina mass ratio in the catalysts was fixed at 0.05:1. The catalyst precursors were prepared from various nickel salts (nitrate, chloride, sulfate, acetate, and lactate) and then calcined at 1073 K for 1 h in oxidative (air), reductive (hydrogen-containing argon), or inert (pure argon) atmospheres to activate the nickel-based catalysts. The effects of precursors and calcination atmosphere on the catalyst activity at low temperatures were studied. We found that the catalysts derived from nickel nitrate had relatively small crystallite sizes of nickel species and provided N-CNFs at high growth rates of 57 ± 4 g-CNF/g-Ni/h at 673 K in the CVD process using 10 vol% hydrogen-containing argon as the carrier gas of acetonitrile vapor, which were approximately 4 times larger than that of a conventional CVD process. The obtained results reveal that nitrate ions in the catalyst precursor and hydrogen in the carrier gas can contribute effectively to the activation of catalysts in low-temperature CVD. The fiber diameter and nitrogen content of N-CNFs synthesized at high growth rates were several tens of nanometers and 3.5 ± 0.3 at.%, respectively. Our catalysts and CVD process may lead to cost reductions in the production of N-CNFs.
