【摘要】采用在Ar气氛保护下裂解FePc制备出一种树状取向碳纳米管阵列(ACNTA),这种种特殊结构是由ACNTA裂缝自组装而成。在生长过程中裂缝处能获得更多的催化剂和碳源,因此自身能够持续发展,且裂缝以60°或120°夹角再次分裂,最终形成树状结构。更多还原

【Abstract】 A tree-branch-like structured ACNTA was obtained by pyrolysis of FePc under Ar ambient.This special pattern of ACNTAs was formed by self-assembling of ACNTAs along the cracks.During growth,the carbon nanotubes(CNTs) along the fissure could receive more catalyst resource and be deposited with more carbon than others,which enables ACNTA cracks to continue to develop.The pattern of the tree-branch-like structure is formed at angle of 60° or 120° between the branch connections.更多还原
