Abstract

In order to directly determine and compare the interaction strength between one active component (Fe2O3) and six different supports, Mössbauer spectra of the six catalysts under room temperatures 373K, 473K and 573K were recorded. From the temperature dependence of area under the resonance curve and isomer shift (IS) parameter which could be extracted from the resonance spectrum, a lattice vibration related parameter θM was calculated.M values can characterize the strength of interaction forces between Mössbauer Fe atoms and its neighbour atoms of supports, hence the order of interaction strength between Fe2O3 and various supports is obtained.
