Abstract
Rh K-edge and Fe K-edge EXAFS were measured on the Rh-Fe bimetallic catalyst supported on silica, by use of synchrotron radiation. Fe atoms in the Rh-Fe/SiO2 catalyst are concluded to be in the meat1-support interface forming Rh-Fe-O(support) bondings, and anchor Rh particles onto the support surface. On the other hand, Fe atoms in the Pd-Fe/SiO2 catalyst are uniformly distributed in the matal particle forming a Pd-Fe alloy.
