【 摘 要 】

2D/2D heterojunction of flower-like MoS2 nanosheets anchored on g-C3N4 was fabricated through a facile hybridization approach, and systematically investigated by various characterization methods (e.g. XRD, SEM, TEM and XPS analysis). Furthermore, tribological properties of g-C3N4/MoS2 composites containing with liquid paraffin were comparatively measured by UMT-2 multispecimen friction and wear tester, and various tribological variables including additive concentration, applied load and rotational speed were also investigated in details. Among all samples, 2%-g-C3N4/MoS2 composites exhibit the minimal friction coefficient (~0.08), and the anti-wear performance is improved obviously. The improvement of tribological properties of the base oil is due to the synergistic effect of g-C3N4 and ultra-thin molybdenum disulfide nanosheets. This study provides a new idea for the design of two-dimensional layered composites with enhanced tribological properties of lubricating oil and matrix.
