Electrical conductivity of iron(III)-exchanged Y zeolites
Abstract
The electrical conductivity of iron(III)-exchanged Y zeolites has been measured in the temperature range 25–600 °C. The specific conductivity decreases with increasing iron(III) exchange. Below 400 °C the conductivity varies markedly with dehydration and may be ascribed to the extent of cation–framework interaction. Above 400 °C thermal conduction predominates. The activation energy for conduction evaluated from Arrhenius plots between 250 and 400 °C increases with increasing iron content.
