Morphological Studies of Bismuth Nanostructures Prepared by Hydrothermal Microwave Heating.

Abstract

Elemental bismuth nanoparticles and nanotubes were obtained via microwave hydrothermal synthesis starting from bismuth oxide (Bi 2 O 3 ) in the range of temperatures 200-220 o C for 10-45 min. The formed nanostructures were studied by scanning electron microscopy (SEM) and transmission electron microscopy (TEM). Relationship between reaction parameters and shape of the formed nanostructures is discussed.
