Boron nitride nanotubes: Nanoparticles functionalization and junction fabrication

Adopting a wet chemistry method, Au and Fe ₃O ₄ nanoparticles were functionalized on boron nitride nanotubes (BNNTs) successfully for the first time. X-ray diffraction pattern and transmission electron microscopy were used to characterize the resultant products. Subsequently, a method was proposed to fabricate heterojunction structures based on the particle-functionalized BNNTs. As a demonstration, BNNT-carbon nanostructure, BNNT-ZnO and BNNT-Ga ₂O ₃ junctions were successfully fabricated using the functionalized particles as catalysts.
