Abstract Molybdenum disulfide (MoS 2 ) hollow microspheres were prepared via a hydrothermal method, which were characterized by XRD, SEM, TEM and UV–vis spectroscopy. The tribological performances of liquid paraffin (LP) mixtures containing these hollow microspheres and the following photo-catalytic degradation behaviors of LP promoted by the worn MoS 2 powders were investigated. The results indicate that 0.50 wt% of MoS 2 hollow microspheres in LP can reduce the friction coefficient of the mixture remarkably, and the photo-catalytic degradation degree of LP also reaches a satisfactory level. MoS 2 serves as both lubricating additives and photo catalysts at the different life stages, and related mechanisms have been discussed, which suggests potential values in the design of novel and sustainable lubricating systems.
