(a) Co 2p spectra of Ag(100)-supported CoO(100) acquired in UHV at room temperature (bottom) and in 1.2 mbar of a 1:2 CO:O2 mixture at stepwise increasing temperature. (b) C 1s spectra corresponding to the Co 2p spectra shown in panel (a). (c) CO and CO2 signals in the exhaust gas from the cell recorded with quadrupole mass spectrometry. |
