The surface composition of a model catalyst for ammonia synthesis based on iron promoted with aluminum and potassium oxides was investigated by X-ray photoelectron spectroscopy. The surface was studied in oxidized, passivated, and reduced states. The

X-ray photoelectron spectroscopy (XPS) is used to show that Fe and Ru on the catalyst surface virtually completely transform into the metallic state during the reduction of the Fe-Ru catalyst. Analysis of the spectra of nitrogen, which is present in

Analysis of the surface composition of a Fe/Ru catalyst containing 40 wt.% of RuO2 in bulk Fe2O3 has been carried out by XPS. It has been shown that after reduction the catalyst surface is enriched with iron.
