Abstract
Thermal transformations of 3[Pt(NH3)4]Cl2–(NH4)2CrO4 (I) and 3[Pt(NH3)4]Cl2–2(NH4)2Cr2O7 (II) mixtures in a solid state have been studied by thermal analysis and mass spectrometry in an inert (Ar) atmosphere and air at temperatures from 40 to 550°C. The chemical and phase compositions of the thermolysis products obtained in argon have been determined: Pt and Cr2O3 in mixture I and Pt, a platinum-based Pt1 – yCry solid solution, and Cr2O3 in mixture II. The thermal transformation products of mixtures I and II in air consist of two phases: Pt and Cr2O3. It has been shown that interactions in the mixtures proceed through the formation of a metallic chromium phase. The materials obtained in this study can find application as catalysts for low-temperature fuel cells, as well as for organic synthesis processes.
