In this work, a green and sustainable strategy for the combined design containing both lubrication and photocatalytic degradation at different stages of base oils has been suggested. More concretely, Fe3O4@MoS2 nanohybrid was prepared and used as an additive for liquid paraffin (LP), resulting in enhanced lubricating properties together with significant photocatalytic degradation performance. The nanohybrid was prepared via a hydrothermal method, which was characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), energy-dispersive spectrometer (EDS), and ultraviolet–visible (UV–vis) spectroscopy. The frictional properties together with photocatalytic degradation behaviors of LP mixtures containing MoS2, Fe3O4, and Fe3O4@MoS2 nanohybrid were under a comparative investigation. The results show that the LP mixture containing 0.08 wt % of Fe3O4@MoS2 nanohybrid can achieve the maximum reduction of friction coefficient; while that containing 0.10 wt % ...
