Abstract
Rh-Sn/SiO2 catalysts prepared by the reaction of (CH3)4Sn with Rh metal particles supported on SiO2 have remarkably high activities for NO-H2 reaction and NO dissociation. The bimetallic surface structure of Rh-Sn/SiO2 composed of an isolated Rh atom surrounded by six Sn atoms, is presented by Rh K-edge and Sn K-edge EXAFS, FT-IR, TEM and CO adsorption.
