Mossbauer, infrared and magnetic characterization of iron/cobalt species in cage structure alumino-silicates (Zeolites)
- 1. The Pennsylvania State University, University Park, PA 16802
Description
Magnetic, Mossbauer, and I.R. studies on S.P. (superparamagnetic) or M.D. (multidomain) particles of Fe and Co species dispersed in cage structure aluminosilicates in relation to syngas (CO+H2) Fischer-Tropsch conversion are reported. The difference in the catalytic activity of such species has been shown to depend upon their degree of dispersion. The carbonyl impregnation gave ultra-fine S.P. Fe3O4, whereas the nitrate impregnation gave M.D. Fe3O4 or omicron-Fe2O3. The active Fe5C2 component was converted to Fe3C during the above reaction
