Title (EN) BORON NITRIDE NANOTUBE PURIFICATION
(FR) PURIFICATION DE NANOTUBES DE NITRURE DE BORE
Abstract:
(EN) Disclosed herein are processes for purifying as-synthesized boron nitride nanotube (BNNT) material to remove impurities of boron, amorphous boron nitride (a-BN), hexagonal boron nitride (h-BN) nanocages, h-BN nanosheets, and carbon-containing compounds. The processes include heating the BNNT materials at different temperatures in the presence of inert gas and a hydrogen feedstock or in the presence of oxygen.
(FR) L'invention concerne des procédés de purification d'un matériau de nanotubes de nitrure de bore (BNNT), tel que synthétisé, pour éliminer les impuretés de bore, de nitrure de bore amorphe (a-BN), de nanocages de nitrure de bore hexagonal (h-BN), de nanofeuilles de h-BN et de composés contenant du carbone. Les procédés consistent à chauffer des matériaux de BNNT à différentes températures en présence de gaz inerte et d'une matière première d'hydrogène ou en présence d'oxygène.
