Morphology-Dependent Ullmann C-O Arylation Using Cu₂O Nanocrystals

Figure 3

Comparative XPS spectra showing simulated peak fittings for the main and satellite peaks of the Cu 2p_3/2 and 2p_1/2 photoelectron lines of all the Cu-oxide nanocrystals: (a) perfect cubic (PC), (b) octahedral (Oct), (c) rhombic dodecahedral (RD), (d) truncated cubic (TC), and (e) fluffy spherical (FS) structures.
