Growth of linear Ni-filled carbon nanotubes by local arc discharge in liquid ethanol. Sagara, T., Kurumi, S., & Suzuki, K. Applied Surface Science, 292:39–43, February, 2014. WOS:000330208500006doi abstract bibtex The cylindrical geometry of carbon nanotubes (CNTs) allows them to be filled with metal catalysts; the resulting metal-filled CNTs possess different properties depending on the filler metal. Here we report the synthesis of Ni-filled CNTs in which Ni is situated linearly and homogeneously by local arc discharge in liquid ethanol. The structural characteristics of synthesized Ni-filled CNTs were determined by transmission electron microscopy (TEM), and the relationship between pyrolysis conditions and the length and diameter of Ni-filled CNTs was examined. The encapsulated Ni was identified by a TEM-equipped energy-dispersive X-ray spectroscope and found to have a single-crystal fcc structure by nano-beam diffraction. The features of linear Ni-filled CNT are expected to be applicable to probes for magnetic force microscopy. (C) 2013 Elsevier B.V. All rights reserved.
