Abstract

The effect of the calcination procedure on the decomposition of the [Pt(NH3)4]2+ complex in a NaX zeolite was studied by mass spectrometry (MS-TPDE) and diffuse reflectance spectroscopy (DRS). The decomposition of the complex took place in two steps. In the first step, under oxygen, the [Pt(NH3)4]2+ complex was first converted to [Pt(NH3)2]2+ complex, accompanied by nitrogen release. In the second step, corresponding to the decomposition of the remaining two amine ligands, NO formation was also observed. Under He, the decomposition also occurred in two steps with H2 liberation. A reaction scheme was proposed for these results.
