Thermal effects in highly dispersed iron catalysts
Get PDFThe Mossbauer spectra of three Fe/SiO2 catalysts with 5 wt% iron content show the presence of several Fe species and display different magnetic behaviours when the precursors are subjected to various thermal treatments. Based on the Mossbauer parameters and CO chemisorption measurements, the average crystal sizes of the catalysts are estimated and discussed in connection with the thermal pretreatment severity and magnetic properties of the samples.Centro de Investigación y Desarrollo en Ciencias Aplicada
