Fabrication and Characterization of Multiwalled Carbon Nanotubes-Alumina Hybrid Compound: Comparison of Various Supported Catalyst

摘要

Hybrid compounds of multiwalled carbon nanotubes-alumina (MWCNT-Al_2O_3) were grown by chemical vapour deposition (CVD) method of methane. The catalyst effect and growth of the synthesis of the multiwalled carbon nanotubes-alumina (MWCNT-Al_2O_3) hybrid compound in three different supported catalysts (Ni, Co and Fe nitrates) were being compared. X-Ray diffraction (XRD) and Field Emission Scanning Electron Microscopy (FESEM) were employed for the characterization of the hybrid compound. The results revealed that the Ni nitrates catalysts showed a better growth rate performance than Co Nitrates and Fe Nitrates. With respect to the diameter of the MWCNT-Al_2O_3, the Fe nitrate showed lengthens in diameter compared to Co Nitrates and Ni Nitrates catalyst. This indicated that the growths of these carbon structures can be controlled and manipulated by the supported catalyst.
