Diffraction patterns collected during the temperature-programmed reduction from 298 to 723 K of the Co/silica gel catalyst in flowing H2 (left), and select diffraction patterns as a function of temperature during the reduction (right) with reference patterns of Co3O4 (black), CoO (red) and f.c.c. Co (blue) displayed below. Inset: close-up of the top of the diffraction peak near 2.59 Å−1 highlighting the shift in peak position as a function of temperature.
