Study of the Interaction of an Iron Phthalocyanine Complex over Surface Modified Carbon Nanotubes

Carbon nanotubes (CNT) were prepared by a modified chemical vapor deposition (CVD) method. The synthesized carbon materials were treated with acidic and basic solutions in order to introduce certain surface functional groups, mainly containing oxygen (OCNT) or amine (ACNT) species. These modified CNTs (OCNT and ACNT) as well as the originally prepared CNT were reacted with a non-ionic Fe complex, Iron (II) Phthalocyanine, and three composites were obtained. The amount of metal complex introduced in each case and the interaction between the complex and the CNT materials were studied with the aid of various characterization techniques such as TGA, XRD, and XPS. The results obtained in these experiments all indicated that the interaction between the complex and the CNT was greatly affected by the functionalization of the latter.

Automated summary

Carbon nanotubes were prepared by modified CVD method and treated with acidic and basic solutions to introduce specific surface functional groups. The treated CNTs were reacted with a non-ionic Fe complex to form three composites, and various characterization techniques were used to study the interaction between them. The results showed that the interaction between the complex and CNT was greatly influenced by the functionalization of the latter.
