Abstract—The catalytic phases containing highly dispersed platinum metal particles on large particles of mixed cobalt oxide were obtained from the binary complex [Co(NH3)5Cl][PtCl4] under hydrothermal conditions. The chemical and phase composition and the morphology of the formed particles were determined using inductively coupled plasma optical emission spectrometry, energy-dispersive X-ray analysis, X-ray diffraction analysis, and scanning electron microscopy. The catalytic phases were deposited onto the metal supports of Kh18N10T and Kh20N80 alloys as chips or metal rubber blocks under autoclave conditions. The catalysts exhibited significant activity in a model reaction of the complete oxidation of propane.
