Controlling the yield and structure of carbon nanofibers grown on a nickel/activated carbon catalyst

Abstract: Carbon nanofibers (CNFs) were grown via the chemical vapor deposition of C2H4 on an activated carbon (AC)-supported Ni catalyst. The texture of the CNF/AC composites can be tuned by varying the growth temperature and by treatment in reducing atmosphere prior to C2H4/H2 exposure. The Ni-catalyzed gasification of the AC support increases the microporosity of the composite and shown to be dominant throughout the composite synthesis especially during reduction, subsequent treatment in reducing atmosphere, and CNF … Show more

“…The growth of CNTs on natural materials is a potential way to achieve environmentally benign and low-cost production. [258] A variety of minerals (such as volcanic lava rock, bentonite, soil, [258] garnet sand, [259] wollastonites, [260] montmorillonite, [261] sepiolite, [262] and vermiculite, [113,210,212] ), biomass-derived materials (such as activated carbon, [263] black jew's-ear fungus and black sesame seeds [264] ), and industrial wastes (such as red mud [265] and fly ash [266] ), have been used as catalysts and/or catalyst supports for the synthesis of CNTs. Organic natural materials, such as coal, [267] natural gas, [268] liquefied petroleum gas, [269] eucalyptus oil, [270] turpentine oil, [271] camphor, [272] deoiled asphalt, [273] even grass, [274] can serve as the carbon source for CNT synthesis.…”

“…Differing from other natural materials for CNT synthesis, AC may suffer gasification during CVD treatment at high temperatures in the presence of hydrogen. [29] The yield of CNFs on the AC was found to be non-proportional to the amount of iron in the starting AC, which suggests that the iron content in the AC can be buried in the bulk such that not all of the iron content plays a role in the CNF growth. The diameters of the CNFs were typically in the range of 30-300 nm, with a small number having diameters as large as 500 nm.…”

“…Among the catalysts, Ni is characterized by exhibiting the highest catalytic activity in the production of CNFs [9,10]. In most studies, Ni was deposited on widely used supports, such as Al 2 O 3 , SiO 2 , TiO 2 , MgO [11,12], and zeolites [13] in addition to activated carbon [14,15] and carbon nanofibers/nanotubes [16,17]. Herein, we report the use of hydroxyapatite (HAp) as a support for a Ni catalyst to produce CNFs using methane decomposition.…”
