Аннотация:The reaction of [Pt(NH3)4]Cl2 with NH4VO3 in alkaline solution in an autoclave at 190°C was studied. The solid autoclave thermolysis product was characterized by the methods of X-ray phase analysis, scanning electron microscopy, energy-dispersive X-ray spectroscopy, dynamic light scattering, and elemental analysis. The product is represented by two phases: Pt and a Pt3V solid solution in the form of two types of particles of different morphology with a size less than 1 µm. The reaction stoichiometry {9[Pt(NH3)4]Cl2, 18NH4VO3, 18KOH} corresponds to the found amount of free ammonia (14NH3) formed under the selected conditions.
