摘要：我们在400℃下利用溶胶一凝胶法制备了La／Co／Ni／MgO催化剂，用化学气相沉积法（CVD）在650—600℃下裂解乙炔气体生长碳纳米管，研究了载气、还原气体和碳源气体流速对碳纳米管产量的影响。其中，载气流速N2是100mL／min，还原气体流速H2是30mL／min，碳源气体流速c2H4是60mL／min时，催化剂聚合物团簇分散效果最佳，碳纳米管的产量和形貌达到最大。
La/Co/Ni/MgO catalysts ior carbon nanotut）es 400 ℃. Carbon nanotubes （CNTs） were synthesized by chemical vapor deposition （CVD） of C2H4 at 650 -600 ℃. The effect of gas flow rates on the synthesized product was studied. When N2 flow rate was 100 mL/min, H2 flow rate was 30 mL/min and C2H4 flow rate was 60 mL/min, catalyst polymer clusters can be perfectly smashed, then products and increase production were further optimized.
