The paper presents the results of experiments on the synthesis of two-dimensional carbon nano-structures by thermal chemical vapor deposition using iron slugs as catalysts and substrates. The synthesis was conducted at a temperature of 250 ° C, a working pressure of 500 mbar, and a duration of 1 hour. From the SEM results it is evident that a two-dimensional structure is synthesized on the surface layer of the Fe slug with a vertical alignment. According to the detailed morphological characteristics of the results obtained by the scanning electron microscope, the nanostructures are two-dimensional carbon nanostruc-tures, i.e. graphene-like. For a detailed determination of the structure of the obtained samples, a study was carried out by the method of Raman scattering and scanning electron microscopy. According to the Raman spectroscopy results, all spectra show the main carbon peaks D and G. In the high-frequency region of the spectra, second-order peaks D′, 2D and D + G are also observed, indicating the presence of graphene.
