In this paper hybrid nanostructures of molybdenum disulfide (MoS₂) and nickel-modified MoS₂ (Ni/MoS₂) were synthesized in two different ways, that is, by chemical gas phase deposition and magnetron scattering, and their structural and morphological properties were thoroughly studied. Scanning electron microscopy was analyzed to assess the surface morphology and microstructure of the synthesized samples, energy-dispersion X-ray spectroscopy to determine the elemental composition, and phase correspondence with the crystal structure was analyzed using Raman spectroscopy. Scanning electron microscopy analysis revealed the formation of hexagonal symmetric high-crystalline triangular crystals characteristic of layered materials. Elemental mapping confirmed the distribution of molybdenum and sulfur, and the uniform distribution of the nickel layer in the heterostructure. While the Raman spectra show characteristic oscillation modes E 2g ~380 cm -1 and A 1g ~406 cm -1 with a distance Δ ≈ 25.8 cm -1 indicating the formation of the MoS 2 layer, the indicators of two phases of MoS 2 in heterostructure were evidence. These results make it possible to optimize the synthesis conditions by controlling the structure, properties and phase composition of the resulting materials. This, in turn, will expand the possibility of using materials in the future in sensor systems, optoelectronic devices, hydrogen evolution reaction and other catalytic processes. In addition, the NI modification improves the functional characteristics of MoS₂ materials and increases their potential in multidisciplinary application areas.
