Covalently Bonded 2D/0D g‐C3N4/MoS2 Nanocomposites for Enhanced Tribological Properties in Oil.

In current work, by an ordinary one‐step hydrothermal strategy, the covalently bonded graphitic carbon nitride/molybdenum disulfide (g‐C3N4/MoS2) nanocomposites were successfully synthesized. SEM, TEM analyses evidenced the well distribution of MoS2 nanoparticles on g‐C3N4. The covalent bond (C−S bond) between two‐dimensional (2D) g‐C3N4 and zero‐dimensional (0D) MoS2 were confirmed by FTIR and XRD. Furthermore, the average friction coefficient and wear rate of g‐C3N4/MoS2 nanocomposites at 0.20 wt % concentration could separately reach up to 27.86 % and 70.87 % reduction by comparing pure oil, benefiting from synergistic lubrication of g‐C3N4 nanosheets plus spherical MoS2. In the work, novel guidance will be provided for the potential application of multi‐dimensional g‐C3N4‐based nanocomposites in lubricating field. [ABSTRACT FROM AUTHOR]
