Phase composition and crystallinity degree of nanostructured products of anode oxidation of manganese(II) ions doped by ions of lithium and cobalt(II)

Abstract

The influence of dopant ions on the phase composition and structure ordering of electrodeposited nanoxides of manganese was investigated. Additives of dopant ions of Li and Co(II) and fluorine-containing electrolytes have been applied for preparation of samples by anode electrodeposition. The samples have been studied by methods of chemical analysis, XRD, TEM, Fourier spectroscopy etc. TEM observation showed that the presence of dopant ions of lithium and cobalt in electrolyte decreased crystallinity of samples, influenced the length and perfection of nanorods, and made structure more defective. The diametres of the nanorods ranged from 10 to 20 nm.
