Fe-silicalite with low concentration of iron was used in the study of the activation by high temperature nitridation (in the temperature range from 540 °C to 700 °C). Nitrided materials were characterized by means of FTIR and UV–Vis spectroscopy.

A series of Fe-silicalite catalysts with tailored dispersion of Fe sites ranging from almost exclusively isolated Fe ions via oligonuclear cluster to Fe2O3 particles were characterized by UV–vis and ESR spectroscopy. The same catalysts were tested
