Two catalysts, nickel and cobalt, supported on MgO were used for carbon nanomaterials deposition by CO disproportionation. The syntheses were performed at 795 and 900 K in the hydrogen atmosphere. The resulting products were investigated using atomic force microscopy, scanning electron microscopy, and high-resolution transmission electron microscopy. Although in the literature carbon nanofibres are expected to form: in the hydrogen presence, we obtained carbon nanotubes, which were multiwall and twisted with the outer diameter of 10-120 nm and the tube length up to 10 μm. |
