In this work, we report X-ray photoelectron (XPS) and valence band (VB)spectroscopy measurements of surfactant-free silver nanoparticles andsilver/linear carbon chains (Ag@LCC) structures prepared by pulse laserablation (PLA) in water. Our measurements demonstrate significant oxidationonly on the surfaces of the silver nanoparticles with many covalentcarbon-silver bonds but only negligible traces of carbon-oxygen bonds.Theoretical modeling also provides evidence of the formation of robustcarbon-silver bonds between linear carbon chains and pure and partiallyoxidized silver surfaces. A comparison of theoretical and experimentalelectronic structures also provides evidence of the presence of non-oxidizedlinear carbon chains on silver surfaces. To evaluate the chemical stability, weinvestigated the energetics of the physical adsorption of oxidative species(water and oxygen) and found that this adsorption is much preferrable onoxidized or pristine silver surfaces than the adsorption of linear carbonchains, which makes the initial step in the oxidation of LCC energeticallyunfavorable.
