Diffraction patterns collected during the carburization of the reduced Co/silica gel catalyst in 20 bar CO at 523 K as a function of time since hydrogen was removed from the gas stream (left) and diffraction patterns at 0 and 340 min, prior to and post carburization (right) with reference patterns of CoO (black), f.c.c. Co (red) and Co2C (blue) displayed below. |
