line 2 ysis used introduced carbon source. The morphology of the product was observed by scanning electron microscopy (SEM). The morphology of the nickel foam was changed during synthesis, and the sulfur promoter and growth temperature were two important factors influ-electromagnetic characteristics. Therefore, CMCs are small and uniform as possible. However, the prepara-strate and an additional procedure to disperse nickel powders on the substrate, in addition to the preparation of fine uniform nickel powders. In this study, CMCs were synthesized by catalytic decomposition of acetylene at 973–1073 K using nickel foam as the catalyst
