catalytic activity - Opis:
- Two sets of iron oxide samples were synthesized applying different iron(III) precursors (FeCl₃ and Fe₂(SO₄)₃) and calcination temperature (200, 300, and 500°C). The samples were characterized by powder X-ray analysis and the Fourier transform infrared spectroscopy. Depending on the synthesis conditions, samples of iron oxides with different phase composition were obtained: polyphase (α -Fe₂O₃, γ -Fe₂O₃, Fe₃O₄, and α -FeO(OH)) and monophase (γ -Fe₂O₃ or α -Fe₂O₃) ones. For the samples of homogeneous composition, it has been found that the activity of γ -Fe₂O₃ in the reaction of ozone decomposition at ozone concentration in gaseous phase of 1 mg/m³ is much higher than the activity of α -Fe₂O₃.
