Abstract:
Carbon erosion of bulk metals and alloys in a carbon-containing atmosphere can be used as an
effective tool for the targeted synthesis of carbon nanomaterials. In this study, a set of bulk Ni0.89Cu0.11 (11 at % Cu)
alloys has been synthesized by the mechanochemical alloying of metal powders in an Activator 2S planetary
mill. The synthesized samples have been studied as precursors of catalyst for the synthesis of carbon nanofibers (CNFs) from ethylene at 550°C. The effect of the activation time on the particle morphology and phase
composition of the alloys, the kinetics of growth, and the carbon product yield in C2H4 decomposition has
been studied. For the most active samples, the CNF yield has exceeded 100 g/gcat within 30 min of reaction.
The early stage of carbon erosion of a bulk Ni0.89Cu0.11 alloy has been studied by electron microscopy methods. It has been found that the nucleation of carbon fiber growth active sites occurs during a short-term contact of the sample with the reaction mixture (less than 1 min); the complete disintegration of the alloy is
observed in a few minutes. The carbon product is represented by nanofibers having a submicrometer diameter
and characterized by a dense “stacked” and coaxial-conical packing of graphene layers. The material has a
developed specific surface area (140–170 m2/g) and a low bulk density (less than 30 g/L).
