Ͷ¸å·µÐÞ£¬Éó¸åÈË˵: XPS experimental details are not correct. XPS spectra shown in the manuscript are not acquired with Mg Ka X-ray source. The instrument name sounds strange. The intensities of the C1s and O1s peak in survey spectrum (Fig 2a) do not correspond to the «trace amount» of carbon and oxygen. Such intensities would give more than 10 at.% of those elements on the surface. Hydrocarbons do not contain oxygen, so their adsorption on the surface can not explain the presence of O1s peak in the survey spectrum. It looks like the Ag3d spectrum deconvolution into components (Fig 2c) is not correct at all. If we sum Ag+ and Ag0 components the resulting curve will not fit experimental spectrum. This experimental spectrum consists of two symmetrical lines (Ag3d5/2 and Ag3d3/2), which would be easily fitted only with one component for each line. For example Ag+ component provides a good fit for Ag3d5/2 line in the spectrum except that we should increase Lorentzian and decrease Gaussian profile contribution to the component. As a result the Ag3d spectrum does not confirm the presence of two chemical states of Ag atoms on the surface of studied sample.
