“…[39] Similar phase transitions for Ni-C nanoscale system were later also observed by some other groups, and also well consistent with our XRD and TEM results. [22,28,30,31,40] It is therefore reasonable to presume that the chemical state of Ni catalyst should be Ni 3 and Ni within the composite nanoparticles was established. (4) CNFs were grown continuously from metallic Ni/C interfaces.…”

“…Es ist von entscheidender Bedeutung zu studieren, wie der graphitische Charakter den Kontakt der Nanopartikel und die katalytische Aktivität des Metalls beeinflusst. Die [6,7] Das Resultat ist carbidisches Nickel (NiC x ). [8,9] HRTEM stützt diese Interpretation, da eine bi- sorption.…”

“…Darüber hinaus zeigen frühere Untersuchungen, dass Versetzungen und Spannungen bei Kohlenstoffaufnahme in Nickel auftreten. [7,11,12] Wir konnten keine Umschließung der Nickelnanopartikel mit Kohlenstoff nach dem Abkühlen auf Raumtemperatur finden. Das deutet darauf hin, dass die Nickel-Kohlenstoff-Bindung relativ stabil ist und dass der Kohlenstoff nicht vom Partikel ausgestoßen wird.…”

“…The bulk phase of an ordered nickel-carbide is metastable and does not form easily. However, the carbon atoms easily dissolve in Ni, which exhibits high carbon solubility [11,12]. An important distinguishing characteristic of Ni compared to other transition metals is that it forms an ordered surface carbide.…”
