Ionic liquid stabilized Ag@C composite for improvement of triboactivity

Enhancement of Triboactivity of Nanolamellar Graphitic-C3N4 by N-Doped ZnO Nanorods

“…A little shift in the peaks indicates that the zinc oxide nanorod might have tribosinterized at the tribosurfaces. Besides, the iron of the steel surface is oxidized to ferric oxide, as revealed by the presence of peaks in the Fe 2p spectrum for Fe 2p 3/2 (710.5 eV) and Fe 2p 1/2 (724.2 eV). − Thus, based on the characterization of tribofilm by XPS spectra, it may be inferred that tribofilm is made up of the adsorbed organic contents of g-C 3 N 4 , N–ZnO, and tribochemically oxidized Fe 2 O 3.…”

“…Employing lubricants with additional friction modifiers produces encouraging results. An extensive overview of literature proclaims that several types of nanomaterials such as nanoparticles, nanosheets, or nanocomposites have been used for the purpose owing to their fast tribo-action. − Nowadays, carbon-based materials such as graphene, fullerene, and carbon nanotubes are the center of attention in this innovative research area. − From our laboratory, too, carbon microspheres, , reduced graphene oxide, and their composites with nanoparticles, doped nanoparticles, or nanosheets have been recently documented as tribologically active materials. − A carbon nitride polymer of high thermal stability possessing graphitic structure g-C 3 N 4 with weak van der Waals forces amid the 2D-nanosheets appears to be very influential in the field. Still, it has been seldom studied. , Zhu et al have described the antiwear performance of bulk g-C 3 N 4 with polyvinylidene difluoride (PVDF) .…”

Tribological activity of ionic liquid stabilized calcium-doped ceria nanoparticles

“…The obtained blackish ash was calcined at 400 C in air for 2 h to yield the CCO. 22,34 Synthesis of IL modified Ca-doped ceria nanoparticles. Ionic liquid [(1-decyl 3-methyl imidazolium bis(trifluoromethylsulfonyl) imide] and CCO, both 0.5 g each in 20 mL DMF, were ultrasonicated separately for 1 h. The solutions were mixed and stirred overnight at room temperature.…”

“…21 Recently, we have found excellent tribological activity of ionic liquid stabilized Ag–C composite. 34…”

“…Antiwear performance of phosphoniumbased ionic liquids mixed with stabilized oxide nanoparticles in PAO and 5w40 has been reported by Valbe et al 21 Recently, we have found excellent tribological activity of ionic liquid stabilized Ag-C composite. 34 Given the above, it appeared us intriguing to synthesize calcium-doped ceria (CCO) nanoparticles (NPs), modify their surface with sodium dodecyl sulfate, 1-decyl-3-methyl imidazolium bis(trifluoromethylsulfonyl) imide and compare their tribological efficiency in paraffin oil (PO).…”
