摘要：

The ion exchange of Fe3+ with sodium in NaZSM-5 was performed with a maximum exchange level of 90% at 25°C. Subsequent exchange of the sodium for NH+ 4 ions was made with no loss of iron, but the thermal decomposition necessary for conversion of these ammonium ions to protons leads to reduction of Fe3+ to Fe2+. These phenomena were monitored by e.s.c.a., Mössbauer, i.r. of adsorbed pyridine, and temperature-programmed reduction. © 1990 Butterworth-Heinemann.
