Synthesis of nanoscale nickel(II) and cobalt(II) sulfides

Resumo

Ranges of stability and regions of the stoichiometric stability of sulfide phases of nickel(II) and cobalt(II) are determined in water–salt solutions. Regions of the homogeneity of NiS and CoS monosulfides are considered. The composition of a microemulsion used as a nanoreactor for synthesizing sulfides is determined, and its phase diagram is plotted. The results from estimating the size of the obtained nanocrystals are presented.
