Carbon Deposition on Iron–Nickel during Interaction with Ethylene–Hydrogen Mixtures

Growth of Filamentous Carbon from the Surface of Ni/SiO2 Doped with Alkali Metal Bromides

“…It must, however, be stressed that the level of carbon deposition was strongly dependent not only on the nature of the dopant(s) but also on the dopant loading and reaction temperature. Indeed, reaction temperature has been shown elsewhere to have a considerable impact on the growth of ordered filamentous carbon (57,(59)(60)(61)(62). As LiBr doping produced the only appreciable promotion of carbon growth, the effect of Li loading (from 0.1 to 6% w/w) was considered in some depth and the results in terms of the temperature dependence of yield are presented in Fig.…”

Carbon nanofibers grown on metallic filters as novel catalytic materials

“…Another explanation relates to the crystalline structure of the carbon nanofibers. Park et al [26] showed that the CNFs produced by decomposition of C 2 H 4 -H 2 mixtures with bimetallic Ni/Fe catalyst, have an increased fiber crystallinity in the case of a higher nickel content. This confirms the importance of catalyst composition on fibers morphology.…”

Synthesis and Protium Absorbing Properties of Vapor Grown Carbon Nano-Fibers Grown by Fe-based Catalyst

“…It is well known that the diameter of VGCFs is governed by the size of catalyst particles. 4,5,11) The size of catalyst particles fracturing Fig. 5.…”

“…The different crystal structure of VGCFs will be formed by varying the composition of catalysts and reactant gas, temperature, and other experimental conditions. 4,5) In addition, diameter of the fibers is determined by the size of catalyst particles. 6) So, the synthesis of VGCFs requires the nanoscale-size catalysts.…”
