Fig. 2: Analysis of time-resolved O 1s data recorded at 100 mbar before and after event-averaging.
From: Stroboscopic operando spectroscopy of the dynamics in heterogeneous catalysis by event-averaging
a, b Image plots of time-resolved O 1s data acquired with 17 Hz and a photon energy of 4.6 keV before and after event-averaging 533 pulses. c, d Single spectra recorded along the dotted lines i and ii in panels (a, b) including curve fitting for the event-averaged spectra. Components are defined in panel (b). e Relative gas composition, PdOx O 1s intensity signal, and binding energy position of Pd 3p3/2 peak as obtained by curve fitting all spectra in panel (b). Relative gas composition is shown on vertically stacked y-axises. The following colours and markers are used in panels (d, e): O2(g) red, CO(g) grey, CO2(g) purple, Pd 3p3/2 binding energy position blue squares, and PdOx oxide intensity orange squares.
