(a) Fresh sample 2D PXRD detector image. The white arrows mark the rings originating from the Co3O4 phase in the fresh, oxidized catalyst. (b) In situ PXRD 1D profiles plotted as a function of temperature; in the PXRD pattern at 120°C is the first PXRD scan after adding H2. (c) Integrated temperature-resolved PXRD patterns during the reduction process in N2/H2 at 60 bar. (d) Zoom PXRD patterns of Fig. 5[link](b) (2.8–3.6 Å−1 region).
