AGO-C(n)/MoS2 composites are synthesized by a facile and effective hydrothermal method. Different mass ratios of AGO-C(n) to MoS2 are prepared for producing AGO-C(n)/MoS2 composites and their tribological properties at different weight percentages in Group III petroleum-based oil are investigated. The as-prepared composites are characterized using Fourier transform infrared (FTIR), field emission scanning electron microscope/energy dispersive X-ray (FESEM/EDX), Raman, X-ray diffraction (XRD), and X-ray photoelectron spectroscopy (XPS). The performance of the AGO-C(n)/MoS2 composites as lubricant additives is investigated on four-ball testers. The results indicate that AGO-C(n)/MoS2 could improve the friction-reduction and antiwear properties of the petroleum-based oil. In particular, the AGO-C14/MoS2 composite with a 1:1 mass ratio shows the highest reduction of friction coefficient and wear scar diameter by 53% and 63%, respectively. The excellent tribological behavior of the composites is attributed to the synergetic effect and unique layered structure of AGO-C(n) and MoS2.
