Abstract

Three new double complex salts (DCSs) containing [Pt(NO₃)₆]^2- anion and Rh(III) metalorganic cations [Rh(4-pic)₄Cl₂]₂[Pt(NO₃)₆] (1,4-pic = 4-methylpyridine), [Rh(bpy)₃]₂[Pt(NO₃)₆]₃ (2, bpy = 2,2′-bipyridiine) and [Rh(bpy)₃][Pt(NO₃)₆](NO₃)(CH₃COCH₃)(CH₃CN)(H₂O) (3) were prepared and characterised by elemental analysis and infrared spectroscopy. Crystal structures of 1 and 3 were determined using X-ray single crystal analysis. Thermal decomposition of salts 1 and 2 in various atmospheres (He, He/H₂, air) was shown to yield Rh–Pt solid solutions with a Rh:Pt ratio inherited from the starting salt composition. The Rh_0·67Pt_0·33/CeO₂ catalyst was prepared by thermal decomposition of salt 1 supported on a CeO₂ surface. The catalyst was tested in a CO oxidation reaction and demonstrated full conversion of CO from about 145 °C at gas hourly space velocity of 200 000 ml g⁻¹ h⁻¹.
