Phases and crystallization of encapsulated cobalt nanorods inside BN nanotubes
Abstract
<p>Continuous filling of BN nanotubes with Co has been obtained using high-temperature substitution synthesis from C nanotubes; this involves filling of C nanotubes with a Co melt accompanied with simultaneous C→BN conversion within tubular layers. Analytical transmission electron microscopy shows that 3d-transition metals, like Co, do not form compounds inside BN nanotubes; rather they form solid solutions with marginal C, N and/or B doping. Ordering of interstitial impurities in a Co crystal lattice has been frequently observed, which exclusively exhibits a certain threefold superlattice. Structural orientation relationship always exists between fillings and BN nanotubes, indicative of an epitaxial crystallization mode of an encapsulated Co filling on a BN innermost wall template. A prevailing crystallization phenomenon shows a certain {01̄1} plane of cubic Co coincides BN filament with an orientation relation of 〈011〉 <sub>Co</sub>//〈1̄21̄0〉<sub>BN</sub> and 〈455〉<sub>Co</sub>//〈011̄0〉<sub>BN</sub>. This phenomenon possibly interprets the transition metals, Fe, Co and Ni, to be the most effective catalysts for the formation of C and BN nanotubes.</p>
