Post‐processing methods have been widely reported as an effective method to purify and functionalize the surface of carbon nanotubes (CNTs). We used a new Co‐based coordination polymer (CP) as a catalyst precursor to synthesize multi‐walled CNTs (MWCNTs) by the chemical vapor deposition (CVD) method, and examined the use of acidification, carbonization and functionalization treatments in an attempt to achieve experimental conditions which efficiently functionalize the surface of MWCNTs. Our results indicate that post‐processing methods can efficiently tune the quality and purity of MWCNTs, and these methods play important roles in dye adsorption.

钴基配位聚合物衍生的碳纳米管：制备，后处理及其在染料吸附中的应用

后处理方法已被广泛报道为纯化和功能化碳纳米管（CNT）表面的有效方法。我们使用一种新型的基于Co的配位聚合物（CP）作为催化剂前体，通过化学气相沉积（CVD）方法合成多壁CNT（MWCNT），并研究了酸化，碳化和官能化处理的用途，以期达到有效地使MWCNT表面功能化的实验条件。我们的结果表明，后处理方法可以有效地调节MWCNT的质量和纯度，并且这些方法在染料吸附中起重要作用。
