摘要: Multi-walled carbon nanotubes (CNTs) have been synthesized on γ-Al2O3 supported unitary, binary or trinity metal (Fe, Co, Ni) catalysts with benzene as carbon source in the range of 600 to 810 ℃. The growth of CNTs was carried out in a fixed bed flow reactor and the quality of carbon deposits was characterized by transmission electron microscopy. The preparation was optimized and the high-yield production of CNTs has been achieved for three mixture catalysts with the yield of high-quality CNTs higher than 200% within 60 min, reaching a maximum of 278% for 1.51 mmol/g Fe-1.51 mmol/g Co/γ-Al2O3 catalyst. This provides a good alternative for future large scale and low cost production of CNTs for applications.

Abstract: Multi-walled carbon nanotubes (CNTs) have been synthesized on $\gamma$-Al2O3 supported unitary, binary or trinity metal (Fe, Co, Ni) catalysts with benzene as carbon source in the range of 600 to 810 ℃. The growth of CNTs was carried out in a fixed bed flow reactor and the quality of carbon deposits was characterized by transmission electron microscopy. The preparation was optimized and the high-yield production of CNTs has been achieved for three mixture catalysts with the yield of high-quality CNTs higher than 200% within 60 min, reaching a maximum of 278% for 1.51 mmol/g Fe-1.51 mmol/g Co/$\gamma$-Al2O3 catalyst. This provides a good alternative for future large scale and low cost production of CNTs for applications.

Key words: carbon nanotube, chemical vapor deposition (CVD), benzene
