The tribological behavior of two types of nanocrystalline molybdenum disulfide produced from natural molybdenum disulfide by monolayer dispersion in the presence of water (nano-MoS
2
(H
2
O)) and acetonitrile (nano-MoS
2
(CH
3
CN)) is studied. The study of the friction of these materials against polished and ground steels, as well as XPS examinations, show the advantage of the more thermally stable nano-MoS
2
(CH
3
CN), which is primarily due to the origin of low-molecular products adsorbed on the surfaces of nanoparticles.
