Mechanical activation of molybdenum disulfide was used to obtain mechanocomposites. They are precursors for obtaining molybdenum blues. To synthesize molybdenum blues, the obtained mechanocomposites were reacted with ethyl alcohol under the required conditions. The obtained mechanocomposites, as well as molybdenum blues, were characterized by X-Ray diffraction (XRD), Transmission electron microscopy (TEM), IR spectroscopy and X-ray photoelectron spectroscopy (XPS). For example, a number of absorption bands are localised in the low-wave IR region, which are characteristic of the functional groups of the target compounds. The results of X-ray diffraction in combination with the results of transmission electron microscopy, EDS and XPS indicate the fact of formation of amorphous phase with partially reduced molybdenum in oxidation degrees from +5 to +6 on the obtained mechanocomposites. This fact, as well as blue colouring and characteristic peak in the absorption spectrum at 750 nm indicate the formation of molybdenum blue. The approach for obtaining polyoxometallate compounds shows potential as a promising way to obtain stable molybdenum blues.
