In this paper, the problem of synthesis of a hybrid nanostructure based on WS2@MXene and a comprehensive study of its structural properties is considered. The WS2@MXene material was obtained using a two-stage method. First, the Ti3AlC2 MAX phase was treated with hydrofluoric acid to obtain Ti3C2 MXene layered material, then WS2 nanostructures were synthesized by hydrothermal method and the two components were combined by ultrasonic mixing. The samples obtained as a result of the synthesis were studied using X-ray diffraction, scanning electron microscopy, and X-ray photoelectron spectroscopy. X-ray diffraction data confirmed an increase in the hexagonal structure of the WS2 phase and the MXene interlayer space. The morphology images clearly showed the WS2 petals embedded in MXene leaflets, and the results of the chemical bond study clarified the necessary elemental composition of the hybrid. The synthesized material has a hierarchical structure consisting of complex nanotubes and nanowires. This structure provides a high specific surface area, efficient electron transfer, and an increase in the number of active catalytic media. The WS2@MXene hybrid is a promising material for energy storage systems, hydrogen evolution reactions, and gas detection sensors.
