A simple method for preparation of Bi and Sb metal nanocrystalline particles

Bi or Sb nanocrystalline metal particles can very easily be prepared by a solid–solid reaction of the powders of BiCl3 or SbCl3 and KBH4 at room temperature. The characterizations indicate that the resultant is the pure metal-nanoparticles with an average diameter of about 30–80 nm.
