QMS single pulse response of the height‐normalized signals of CO (m/z=28), O2 (m/z=32), Ar (m/z=40) and CO2 (m/z=44) on the pre‐oxidized (O400 treatment: 1 h in 10 % O2/N2 at 400 °C) Au/CeO2 catalyst during simultaneous pulses with CO/Ar and O2/Ar at 180 °C. For better comparison the QMS mass signals were normalized to the same height Reprinted with permission from Ref. [83] © 2013, Elsevier Inc.
