As the catalyst after reduction is extremely active, part of it has been oxidized when transferring to the sample room during experiment, Fe2p occurs displacement and its content is lower that real one. It is worth noting that the more elements of chlorine (Cl) were found on the surface of the catalyst. 

Similar AES of N2 absorbed on W (110) at lOOK was observed. The amount of absorbed nitrogen can be monitored by the peak height of the AES. Nitrogen molecules adsorbed on W, Ni, Fe at 100 K or lower temperatures have two peaks in XPS at around 400 eV and 406 eV, which are interpreted in different ways the peak in 406.6 eV is a molecular adsorption of N2 (a), and the peak in 397.6eV is an atomic adsorption of N (a) on W because the former disappeared while the latter remained at 300 two types of N2 (a) one is an end group, 

N (a) on iron at 290 and 397.5 eV for N (a) on promoted iron at 673 Surface science reviews have been published.
