Abstract: Thermal decomposition of complex salts [M(NH3)4]A (M = Pt, Pd; A = CrO4, Cr2O7) in oxygen atmosphere goes through the stage of formation of the phase MCrO2 with delafossite structure and it’s further decomposition and formation of the chromium oxide(III) and monometallic platinum or palladium. Thermal decomposition of complex salts [M(NH3)4]A (M = Pt, Pd; A = CrO4, Cr2O7) in hydrogen atmosphere proceeds with partial reduction of chromium to an metallic state and the formation of a metal solid solution MxCr1-x (M = Pt, Pd) with a chromium content up to 22 at.% and a chromium oxide(III). Catalytic properties of bimetallic Pt-Cr2O3 and Pd-Cr2O3 composites obtained by thermal decomposition in hydrogen atmosphere at the temperature 500 °C differs a lot from monometallic Pt and Pd in CO TOX and PROX processes. Addition of Cr2O3 boosted oxidative activity of metals probably due to appearance of metal-oxide interface, which is of crucial importance in catalysis.
