Figure 6From: Supported quantum clusters of silver as enhanced catalysts for reduction XPS spectra of supported quantum clusters. XPS expanded spectra in the Ag 3d (a), C 1s (b), S 2p (c), and Al 2p (d) regions of Al2O3@Ag7,8 QCs before (black), after 1st (red) and 3rd cycles (green) of catalysis.Back to article page
