Structure and magnetic response of a residual metal catalyst in highly purified single walled carbon nanotubes

Original language description

Article presents methods for physical analysis of partial steps leading to the removal of residual metal catalyst nanoparticles (NPs) from single walled carbon nanotubes (SWCNTs) and options for detecting negligible amount of metal in samples possessingdiamagnetic response. Based on the previous knowledge of the NP properties included in the commercial SWCNTs, the properties of remaining NPs after the multi-step purification and annealing under static and dynamic vacuum have been investigated. TG, XRD,magnetic property measurements and EXAFS experiments have been done and provided information about the nature of the residual NPs in purified SWCNTs, crucial for further understanding of the purification processes and their improvement. We demonstratedthat even if all macroscopic methods indicate a high purity of the treated sample, a non-negligible amount of the metal may still be present and the metal content has to be examined using local element sensitive probes such as EXAFS.
