Synthesis and Stabilization of Bismuth Nanoparticles in Aqueous Solutions

A technique is developed for the low-temperature synthesis of bismuth nanoparticles in aqueous solutions. UV–Vis spectroscopy, X-ray analysis and dynamic light scattering show that sodium polyacrylate is an effective stabilizer for free nanoparticles. It is selectively bound to the planes of the bismuth hexagonal lattice equivalent to {111} symmetry.
