A simple chemical method was employed to coat carbon nanotubes (CNTs) with a layer of Co-B amorphous alloy. This technique involved a redox reaction using KBH4 as reducing agent and Na-2[Co(OH)(4)] complex as cobalt precursor. The amorphous character of the Co-B alloy was confirmed by high-resolution transmission electron microscopy (HRTEM) and Xray diffractogram analysis (XRD). These coated carbon nanotubes may be of great interest in magnetic research and as highly active catalysts in heterogeneous catalysis.
