The paper presents the experimental results of the hydrothermal synthesis composite materials based on the MoS2 and carbon using different types of detergents (cetyltrimethylammonium bromide and Triton-X) or microporous carbon. The synthesized material was studied by XRD, TEM, and EDS. The investigation of structural and morphological properties of the obtained nanocomposite material shows that the nanoparticles (the average size of about 40 nm) obtained by detergent-assisted procedure have a multilayer crystal ordered superficial layers where quasi-two-dimensional MoS2 layers alternate with amorphous carbon. The annealing at 500oC in argon caused the formation turbostratically stacked layers of crystalline MoS2 with amorphous carbon located in the interlayer space. The core-shall morphology (carbon nanoparticles on the surface of MoS2 clusters) was observed for composite materials synthesized on the base of microporous carbon.
