2D/2D HETEROSTRUCTURE OF FLOWER-LIKE MoS2 NANOSPHERES ANCHORED ON g-C3N4 NANOSHEETS FOR REDUCING FRICTION AND WEAR

Novel 2D/2D structural nanocomposites of g-C3N4/MoS2 with high tribological properties was fabricated through a facile one-step process. The tribological properties of the as-prepared g-C3N4/MoS2 as additives in the HVI500 base oil are evaluated by an UMT-2 multi-specimen tribo-tester and the topography of worn scars was obtained using a common SEM,which indicates the minimal friction coefficient (~0.10) and wear rate (3.86×10-5 mm3 /Nm) and demonstrate the accentuating improvement in reducing-friction and anti-wear properties. The enhanced tribological performance of base oil can be ascribed to the combination of g-C3N4 and spherical-like MoS2 to share the role of synergistic lubrication. More importantly, our work provides a fresh insight into designing lubricating oil additive and extending the 2D/2D structural nanocomposites.
