摘要：

The thermal decomposition of di-ammonium hexachloroplatinate ((NH4)(2)[PtCl6]) to metallic platinum has been investigated by time-resolved in situ XAS measurements at the CI K- and Pt L-III-edge. Spectra at the CI K-edge were recorded utilizing an energy dispersive monochromator (EDM), while the Pt L-III-edge spectra were recorded using a double crystal monochromator. By analysing the energy shift of the Cl K-edge a reaction intermediate has been observed at about 310 degrees C. Fingerprinting arguments indicate that this intermediate could be cis-platin or some other platinum amine complex.
