a XRD patterns, b Raman spectra, and c high-resolution Ag 3d XPS spectra of Ag NCs and aryl sulfur-modified Ag NCs. d Ratio of Ag+ to Ag0 in Ag NCs and aryl sulfur-modified Ag NCs derived from high-resolution Ag 3 d XPS spectra. The analysis was performed at least three times, and the mean values are shown with the standard deviation as error bars. e Ag K-edge XANES, f Fourier transform of Ag K-edge EXAFS spectra, and g WT-EXAFS plots of Ag NCs and aryl sulfur-modified Ag NCs.
