1. A method for preparing a boron nitride nanotube (BNNT)-nanoparticle composite, the method comprising:
subjecting a source of hydrogen, a source of boron, a source of nitrogen and a nanoparticle precursor that is a non-catalytic metal or a non-catalytic ceramic to a stable induction thermal plasma to form a reaction mixture in the plasma; and
cooling the reaction mixture to obtain the BNNT-nanoparticle composite with nanoparticles attached to on outer surface of BNNTs.
