Illustration of the D&P technical challenges associated with the time evolution of the experimental conditions. (a) Schematic sectional view of the thin film highlighting the origins of the electrolyte film dynamics during the in situ/operando experiment; (b) and (c) are XP spectra of the same Pt/CsOH 1 M interface at different times after pulling the electrode from the electrolyte at −0.75 V and +0.35 V versus Ag/AgCl, respectively. hν = 1800 eV, P = ∼15 mbar. (d) Schematic sectional view highlighting possible accumulation of water in front of the nozzle, presumably due to the local radical production and their dilution by osmosis. (e) and (f) are successive O 1s and Au 4f XP spectra of an Au foil, physically disconnected from the electrolyte. hν = 1800 eV, P = ∼20 mbar.
