摘要

摘要使用螯合剂，采用聚合络合前驱体（PCP）法合成了用于碳纳米管生长的金属氧化物催化剂（MOCs），其一般组成为 Fe2Co/CaCO3。已经证实，用聚合络合前驱体方法合成的金属氧化物催化剂比用溶胶-凝胶技术合成的 MOCs 的效果要好一个数量级。使用两种配体获得的 MOC 的生产率明显高于单配体样品的效率。研究结果表明，在使用聚合络合物前驱体方法合成用于生长 CNT 的金属氧化物催化剂时，除了使用碳水化合物外，还可以使用多种不同性质的螯合剂（多元醇、羟基酸、氨基酸等），从而影响 MOCs 前驱体结构的预组织阶段、金属氧化物催化剂的特定生产率以及碳产品的质量成分。

Abstract

Metal oxide catalysts (MOCs) for the growth of carbon nanotubes with the general composition Fe₂Co/CaCO₃ were synthesized by the polymerized complex precursor (PCP) method using chelating agents. It has been established that metal oxide catalysts synthesized by the method of polymerized complex precursors are an order of magnitude more effective than MOCs synthesized by the sol-gel technology. The productivity of MOCs obtained using two ligands is significantly higher than the efficiency of monoligand samples. As a result of the study, it was found that the use, in addition to carbohydrates, of a wide range of chelating agents of various natures (polyalcohols, hydroxy acids, amino acids, etc.) in the synthesis of metal oxide catalysts for the growth of CNTs by the method of polymerized complex precursors is advisable and makes it possible to affect the stage of preorganization of the structure of MOCs precursor, specific productivity of metal oxide catalysts as well as qualitative composition of carbon products.
