A facile synthesis of nitrogen-doped bamboo-shaped carbon nanotubes by catalytic decomposition of 2-aminopyrimidine over Fe@MgO catalyst through chemical vapor deposition method

In this work, nitrogen-doped bamboo-shaped carbon nanotube (nitrogen-doped CNT) was prepared using the Chemical Vapor Deposition Method (CVD). For the first time, 2-aminopyrimidine (a carbon and nitrogen resources) was used as a precursor over Fe@MgO catalyst and employed in CVD. The prepared CNT was characterized via elemental analysis, Fourier Transform Infrared Spectroscopy (FT-IR), Energy Dispersive X-ray Spectroscopy (EDX), Transmission Electron Microscopy (TEM), X-ray Diffraction (XRD), Raman Spectroscopy and Scanning Electron Microscope (SEM). The amount of nitrogen in the prepared CNT was about 5.8%. The FT-IR spectrum reveals the presence of C–N and C = N bonds in the prepared CNT structure. The prepared CNT has bamboo-like structure with a diameter of less than 100 nm.
