Abstract
The role of iron in the catalytic properties of ZSM-5 ferrisilicate an alogs in the oxidation of benzene to phenol by dinitrogen monoxide has been studied within a wide range of iron concentrations (from 0.003 t o 4.8 wt.-% Fe2O3). The samples of the Fe-Si system with optimal iron content, as well as previously studied Fe-Al-Si samples of the same ze olite structure, were found to be far superior to known catalysts. A r eaction mechanism is suggested, where the active form of the surface o xygen produced by dinitrogen monoxide decomposition is of key importan ce. Zeolite acidity was tested and its role in the catalytic activity is discussed.
