Abstract

An XP, IR and UV–VIS spectroscopy study was carried out to characterize the compositions of molybdophosphate heteropoly anions with Ir(III) or Rh(III) hydroxo–chloro complexes, such as Ir1.1Cl2.4O x H y ·(PMo12O40)·16.0 H2O, where x is the number of oxygen atoms in the coordination sphere of iridium, and also mixed-valent species containing partially reduced and dehydrated heteropoly acid of suggested composition (Ir0, IrIII) n Cl m O x H y (PMo 12−p VI Mo p V O40−p/2) (on the average, n ≈ 1, m < 1, p ≥ 4). The mixed-valent Ir containing species showed stable activity in the gas-phase oxidation of benzene by O2–H2 mixture.
