Fig. 4: tr-APXPS of CO oxidation of Pt(111) when pulsing CO at 50 Hz into a stream of O2 where CO2 production can be controlled by tuning the pulsing parameters thus changing the surface-mediated response.
Constant CO2 production was achieved as shown in 2D plots of the a C 1s GP, b O 1s, and c C 1s spectra, along with an analysis of d O 1s intensity trends.
