Fig. 2: Isobar C 1 s spectra under reaction conditions.
From: In-situ probing of the Fischer-Tropsch reaction on Co single crystal surfaces up to 1 bar

We show Co\(\left(0001\right)\) at a 500 mbar and b 200 mbar. In c we show 150 mbar on Co(\(10\bar{1}4\)). All mixtures are 1:2 CO:H2. Subplot d shows a comparison of 406 K data as function of pressure on the Co\(\left(0001\right)\) crystal, and subplot e displays a direct comparison of stepped Co(\(10\bar{1}4\)) and flat Co\(\left(0001\right)\) crystals at 406 K. All y-axes have the same scaling. Data has been normalized according to SI Section S6c. The color code is the same as in Fig. 1b/e. Source data are provided as a Source Data file.
