Abstract
In - situ EXAFS technique was successful by applied for the first time to observe the molecular reaction intermediate for NO - H-2 reaction on highly active Rh - Sn/SiO2 catalysts. The EXAFS data, with. the aid of FTIR, revealed the existence the bent - type NO with the bond dist ance of 0.256 nm with Sn atoms (Rh - NO - Sn) on the bimetallic surfac e in the steady - state reaction conditions. The tilted NO was dissoci ated to form Sn - O bond at 0.205 nm.
