Abstract
A new class of highly active polymetallic catalysts for deep oxidation based on iron with admixtures of other d-metals and rare earths has been developed. The precursors of the catalysts are multicomponent intermetallides obtained by selfpropagating high-temperature synthesis (SHS). The XPA spectra, specific surface, and the morphology of the surface according to the SEM results are studied. The catalytic properties are studied using the example of deep oxidation processes of carbon monoxide and propane. It has been shown that two-level metal–oxide nanostructures are common features of the surface for the catalysts studied. The lowest level represents granules 10–30 nm in diameter, of which flat hexahedrons are built with a diameter of about 1 μm and a thickness of ≤100 nm.
