Synthesis, argon/hydrogen storage and magnetic properties of boron nitride nanotubes and nanocapsules

摘要

Boron nitride (BN) fullerene materials such as nanotubes, nanocapsules and nanocages were synthesized from LaB_6, Co, Pd, Ti, Ni and Cu with boron powder by using an arc-melting method. For the BN nanocapsules with Co and CoO_x nanoparticles, argon element was detected by energy dispersive X-ray spectroscopy, and the nanocapsules showed superparamagnetic property. Thermogravimetry/differential Thermogravimetric analysis of BN nanomaterials produced from LaB_6 and Pd/boron powder showed possibility of hydrogen storage of approx 3 wt. percent.
