【摘要】 用催化裂解法批量制备碳纳米管时，反应温度，反应时间，原料气体流量和催化剂用量等因素对碳纳米管的产量、转化率、微观组织形态有较大影响，其中以反应温度的影响最大。在一定范围内调整裂解温度，可以得到宏观上产量、转化率较高，微观上组织形态较好的碳纳米管。更多还原

【Abstract】 All of the experiments involved in this thesis used the method of catalytic pyrolysis of acryl to synthesize Carbon Nanutubes (CNTs). In a stainless steel tube, the reaction room, catalytic pyrolysis of acryl over quartz boats coated uniformly with Ni－ Al－ diatomite catalyst in the range of 400～ 850 ℃ resulted in the formation of a large number of CNTs which were observed directly by transmission electron microscopy(TEM). The reaction temperature, one of the main factors which affect the productivity of CNTs, is studied systematically. The result of the experiments showed that the reaction temperature had comparatively strong effect on the productivity of CNTs. All the parameters about the reaction temperature indicated above were optimized.更多还原
