“…The signature 2D and D+G peaks for graphene films at 2700 cm -1 and 2900 cm -1 respectively are present at a relatively lower compared to those D and G peak. This 2D peak originates from second-order Raman scattering, and its intensity and FWHM are important in determining the thickness and number of graphene layers [8]. The ratio of the low-intensity 2D…”

“…Because of their hydrophobicity, carbon-based quantum dots can decrease their friction coe cient by 33% when dispersed in deionized water for use [23,24]. The carbon dot nanobearing and nano-lling effects can enhance its anti-friction and wear-resistance properties [25]. At present, GQD treats interest as an additive to polyols.…”

N-doped graphene oxide quantum dots (NGOQDs) with MoS2 and Al2O3 nanocomposites were prepared by solvothermal method. The morphology and the composition and structure of the prepared composites was characterized by TEM, XRD, Raman, ATR-FTIR and XPS. Tribological behavior of NGOQDs-MoS2 and NGOQDs-Al2O3 nanocomposites as lubricant additive in aqueous glycerol were studied. Through experiments and MD simulations, the tribochemistry-induced lubrication mechanism was disclosed. The results shows that the combination of NGOQDs and hydrated glycerol can significantly improve lubrication performance, and the addition of NGOQDs-MoS2 and NGOQDs-Al2O3 nanoparticles can further improve tribological properties. The formation of a tribofilm through tribochemical induced lubrication mechanism improves the wear resistance of metal surfaces.
