Abstract


The hydrodynamic characteristics of bimetallic Ag/Cu and Co/Ag nanoparticles stabilized by chitosan were determined. The polydispersity indexand the diameter of nanoparticles were observed to decrease in contrast tothe original polymer during the creation of chitosan stabilized bimetallicnanoparticles, decreasing from 0.342 to 0.12±0.04 and 2.5 micron to 180nm, respectively. However, the diffusion coefficient of chitosan was increased from 0.2 cm2 /s to 2.71 cm2 /s during the production of stable bimetallic nanoparticles. The lack of absorption bands at 500 nm and 700 nm-900 nm in the UV spectra of the samples suggests that in the presence ofa reducing agent, copper (II) and cobalt (II) ions undergo full reduction.The relationship between the synthesis conditions and the kind of structureof bimetallic nanoparticles “core-shell” has been discovered. Silver atomshave been shown to be both a core and a shell, depending on the synthesisconditions and chemical nature of metal ions.
