Carbon nanofibers (CNFs) containing different proportions of Ni and Si were produced from methane decomposition in a fluidized bed reactor with a nickel–copper based catalyst. They were subjected to heat treatment in the temperature interval 1800–2800°C for the purpose of studying the influence of the inherent metal species on their ability to graphitize. The participation of Ni and Si species on...
The electrochemical performance as anodes in lithium-ion batteries of graphite-like materials that were prepared by high temperature treatment of carbon nanofibers (CNFs) is investigated by galvanostatic cycling. These CNFs were produced in the catalytic decomposition of methane (CDM). By this process, a valuable free-CO 2 hydrogen was simultaneously produced. The graphitized CNFs have provided...
The catalytic effect of the inherent Ni and Si on the graphitization of carbon nanofibers produced by catalytic decomposition of methane is reported. The participation of the inherent Ni and Si metals as co-catalysts in the graphitization of the carbon nanofibers through the formation of Ni 2 Si and SiC was inferred. Taking advantage of this catalytic effect, graphite materials showing structural...
