The catalytic synthesis of carbon nanotubes (CNTs) using CeFeMgO catalysts represents a promising avenue for achieving efficient and controlled carbon nanotube growth. The CeFeMgO catalysts were prepared by solution combustion techniques and the growth of CNTs was obtained from the chemical vapour deposition (CVD) method. The X-ray diffraction (XRD), high-resolution scanning electron microscopy (HR-SEM),w energy dispersive X-ray spectroscopy (EDAX), transmission electron microscopy (TEM), thermogravimetric analyzer (TGA), BET, particle size distribution. were employed to characterize the morphology, crystallinity and composition of the synthesized CNTs. Results indicate that the study reveals the robust catalytic activity that facilitates the formation of high-quality carbon nanotubes (CNTs), highlighting the efficiency of CeFeMgO catalysts in promoting CNT growth and elucidating the structural aspects crucial for optimizing carbon nanotube production. The results demonstrate uniform carbon nanotube dimensions, excellent crystallinity and minimal defects, highlighting the efficacy of catalyst in achieving controlled and efficient carbon nanotube synthesis. This study enhances the comprehension and utilization of CeFeMgO catalysts in the synthesis of carbon nanomaterials.
