Abstract
Abstract In current work, by an ordinary one‐step hydrothermal strategy, the covalently bonded graphitic carbon nitride/molybdenum disulfide (g‐C 3 N 4 /MoS 2 ) nanocomposites were successfully synthesized. SEM, TEM analyses evidenced the well distribution of MoS 2 nanoparticles on g‐C 3 N 4 . The covalent bond (C−S bond) between two‐dimensional (2D) g‐C 3 N 4 and zero‐dimensional (0D) MoS 2 were confirmed by FTIR and XRD. Furthermore, the average friction coefficient and wear rate of g‐C 3 N 4 /MoS 2 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‐C 3 N 4 nanosheets plus spherical MoS 2 . In the work, novel guidance will be provided for the potential application of multi‐dimensional g‐C 3 N 4 ‐based nanocomposites in lubricating field.
