| 摘 要： | 以苯和乙醇的混合溶液为碳源，二茂铁、噻吩和氢氧化钠为催化剂体系，采用催化裂解法制备出多壁碳纳米管，并研究了氢氧化钠的添加对多壁碳纳米管结构的影响。结果表明：随着反应体系中氢氧化钠质量浓度的增加，多壁碳纳米管的外径显著减小，内径略有增大。

| Abstract: | Multi-walled carbon nanotubes (MWCNTs) have been synthesized by a catalytic pyrolysis method using a mixture of benzene and ethanol as carbon sources, and ferrocene-thiophene-sodium hydroxide (NaOH) as the catalyst system. The effect of the NaOH concentration in the reaction mixture on the structure of the MWCNTs was investigated. The results indicated that the outer diameter of the MWCNTs decreased significantly with increasing NaOH concentration, whilst the inner diameter increased only slightly. |
