Abstract

The use of through canals of porous glass as a re-action chamber ensures the existence of an upper bound on the size of bismuth particles being synthesized. The powder formed by these particles includes, together with the stable rhombohedral form of bismuth, the nanocrystalites of hexagonal modification. The nanoforms of bismuth obtained by various methods typically possess the stable rhombohedral structure [1-10]. However, the parameters of the crystal structure can deviate from their usual values when nanoparticles are formed in the narrow canals of porous glass (PG). Accordingly, this work considers an approach involving the binding of bismuth oxide as an insoluble precursor in the matrix of a PG, followed by Bi2O3 reduction by glycerol and removal of bismuth nanoparticles from the pores.
