Pentagonal Cobalt Boride Nanoparticles on the Polystyrene Granule Surface
The morphology and structure of cobalt-containing nanoparticles Co2B on the surface of polystyrene microgranules have been investigated by a set of structural methods, including X-ray diffraction, electron diffraction, and transmission electron microscopy. It has been established that the nanoparticles are 30–100 nm in size and have a spherical or pentagonal shape. It is shown that the nanoparticles have a cluster structure with an individual cluster size of several nanometers. The growth of pentagonal Co2B nanoparticles on the microgranule surface may be due to the processes similar to those occurring in wildlife during the formation of organisms and plants of pentagonal shape.
