Реферат: High-active Fe–Al and Cu–Fe–Al nanocomposite catalysts were synthesized by fusion of aluminium, iron, and copper salts and then tested in the oxidation of CO. It was found that the activity of Fe–Al catalysts depends on the Fe concentration and the maximum is achieved when the Fe2O3 content is approximately 82 wt%. The addition of Cu leads to a significant increase in activity. Using adsorption techniques, X-ray diffraction, X-ray absorption spectroscopy, and Fourier-transform infrared spectroscopy, morphology, structure, and chemistry of the catalysts were studied. It was shown that the Fe–Al catalysts consist of Fe2O3 and Al2O3 phases mainly. Alumina is in an amorphous state whereas iron oxide forms nanoparticles with the protohematite structure. The Al3+ cations partially dissolute in the Fe2O3 lattice. X-ray absorption spectroscopy indicated that the Cu–Fe–Al catalysts in addition contain CuO and CuFe2O4 oxides in an amorphous state.
