Noble metal nanoparticles such as palladium and platinum have received considerable attention due to their high catalytic activity in organic chemistry and electrochemistry. However, nanoparticles are generally agglomerated by van der Waals force, which reduces the specific surface area, resulting in deterioration of the catalytic activity. In order to solve this problem, we have developed a technique to inhibit aggregation of nanoparticles by attaching the particles to a support. Boron nitride nanotube (BNNT) was used as a support because of its excellent catalytic activity as well as resistance to oxidation and thermal stability. By a sonochemical reaction, metal nanoparticle was synthesized from noble metal ion and embedded on the BNNT without reducing agents by ultrasonic energy. Noble metal nanoparticle embedded BNNT can be used in a variety of catalyst applications. |
