AB  - g-C<sub>3</sub>N<sub>4</sub> has a strong C-N covalent bond within the monolayer and a weak van der Waals 
force between the lamels, which enables it to have similar lubrication properties to other 
two-dimensional layered materials. In this study, a new type of g-C<sub>3</sub>N<sub>4</sub>/MoS<sub>2</sub>/ZnS 
heterogeneous nanocomposites was prepared by a one-step hydrothermal method XRD, 
SEM, FI-IR, and other methods were used to systematically study it. Furthermore, a 
ball-on-disk
 tribometer
 extensively
 examined the tribological behavior of 
g-C<sub>3</sub>N<sub>4</sub>/MoS<sub>2</sub>/ZnS heterojunction in pure oil. The relationship between applied load and 
rotational speed on performance is also revealed. Compared with g-C<sub>3</sub>N<sub>4</sub> and 
g-C<sub>3</sub>N<sub>4</sub>/MoS<sub>2</sub> nanocomposites, g-C<sub>3</sub>N<sub>4</sub>/MoS<sub>2</sub>/ZnS has better frictional properties. It is 
worth noting that when g-C<sub>3</sub>N<sub>4</sub>/MoS<sub>2</sub>/ZnS is in the base oil mass ratio at 1.0 wt.%, the 
friction coefficient is reduced by 49%. In addition, g-C<sub>3</sub>N<sub>4</sub>/MoS<sub>2</sub>/ZnS ternary 
heterojunction exhibits better tribological properties than g-C<sub>3</sub>N<sub>4</sub>/MoS<sub>2</sub>/ZnS mixture, 
expanding their practical applications in industry and agriculture.
