Abstract
In situ X-ray absorption near edge structure (XANES) investigations were carried out at chlorine K edge and palladium L 3 edge to study the mechanism of the thermal decomposition of ammonium hexachloropalladate. The spectra show a characteristic feature for the initial step that might be explained as the formation of the precursor via ligand exchange (Cl ⇒ NH3). Multiple scattering calculations (Feff 8) for the Cl K, Pd and Rh L 3 edges were successful in simulating the XANES spectra of the precursor as well as the reference compounds (NH4)2[PdCl4] and (NH4)3[RhCl6].Keywords
