PREPARATION OF HYBRID NANOSTRUCTURES BASED ON WS2 AND MXENE AND STUDY OF THEIR STRUCTURAL PROPERTIES

In this paper, the problem of synthesis of a hybrid nanostructure based on WS 2 @MXene and a comprehensive study of its structural properties is considered. The WS 2 @MXene material was obtained using a two-stage method. First, the Ti 3 AlC 2 MAX phase was treated with hydrofluoric acid to obtain Ti 3 C 2 MXene layered material, then WS 2 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 WS 2 phase and the MXene interlayer space. The morphology images clearly showed the WS 2 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 WS 2 @MXene hybrid is a promising material for energy storage systems, hydrogen evolution reactions, and gas detection sensors.
