O 1 and C 1 photoelectron peaks acquired under APXPS conditions at r.t. (298 K) on Cux=1.5O and at r.t. and at a total pressure of CO2 and O2 (1:1) of 0.7 Torr. The relative abundance of the different chemically shifted components is expressed in percentage of the total integrated area of each photoelectron spectrum.
