Abstract
Carbon nanotubes (CNTs) were synthesized by chemical vapor deposition (CVD). The Seymchan meteorite (metal part) was used as a substrate due to its nanoscale structure and areas with different Ni content. The thermal oxidation experiment with the Seymchan sample was carried out to estimate the oxidation result during the CVD. The study of the samples by scanning electron microscopy and Raman spectroscopy showed that they were covered with Fe2O3 nanorods (30 nm in diameter). After the CVD process, the oxide nanocrystals and CNTs covered the sample. The structural composition affected the growth and morphology of CNTs. The least disordered CNTs were obtained on a taenite surface (an average diameter was 10 nm).
