Abstract:
New complex salts [Pd(NH3)4]3[Ir(NO2)6]2x[Rh(NO2)6]2 – 2x (II–VI) were prepared, which are solid solutions based on double complex salts [Pd(NH3)4]3[Ir(NO2)6]2 (I) and [Pd(NH3)4]3[Ir(NO2)6]2. The obtained compounds were characterized by X-ray powder diffraction analysis, IR spectroscopy, and elemental analysis. The compounds crystallize in the cubic system (space group F43¯c). The thermal behavior of compounds I–VI in various gas atmospheres was investigated. The final products of thermolysis of [Pd(NH3)4]3[Ir(NO2)6]2x[Rh(NO2)6]2 – 2x in reducing (H2) and inert (He) atmospheres were trimetallic porous Pd–Ir–Rh nanoalloys. The final products of thermolysis in an oxidizing atmosphere were mixtures of metal oxide phases with an admixture of a metal phase. The structural and morphological properties of the formed nanoalloys were studied. The obtained solid solutions of double complex salts [Pd(NH3)4]3[Ir(NO2)6]2x[Rh(NO2)6]2 – 2x were used to synthesize alloy nanoparticles on the surface of a γ-Al2O3 oxide support. The catalytic activity and stability of the produced catalyst samples were tested in a model reaction of CO oxidation under forced thermal aging conditions.
