a),b) Time‐resolved in situ DRIFT spectra of OH groups recorded at different times during reaction in ID‐ref 6000 reformate at a) 190 °C‐1 (1, 2, 5, 7, 10, 20, 60, 120, 360, 660, 1000 min) and b) 190 °C‐2 (1, 60, 120, 240, 360, 480, 600 min). Note the intense and broad water bands (3500–3630 cm−1) appearing during the initial reduction of the Ru oxide NPs. c) In situ DRIFT spectra of the different pyrrole covered Ru/γ‐Al2O3 catalysts (steady‐state conditions) at 30 °C, d) accumulated, catalyst‐mass‐normalized amount of desorbed pyrrole during a TPD measurement in N2. e),f) Time‐resolved in situ DRIFT spectra of the COad region recorded at different times during reaction in SR‐ref 6000 at e) 190 °C‐1 phase (1, 2, 5, 7, 10, 20, 60, 120, 360, 660, 1000 min) (e) and f) 190 °C‐2 phase (1, 60, 120, 240, 360, 480, 600 min).
