Pt/MOR-Al2O3 catalysts, with platinum supported from H2PtCl6 and [Pt(NH3)4]Cl2 solutions are investigated in the work with the methods of IR spectroscopy. The received results testify about platinum fixing mainly in channels of a mordenite in case of supporting from an ammine, and its localization on Al2O3 surface when supporting from chloroplatinic acid. Small concentration of the absorption bands referred to bridging CO species on platinum testify about high dispersion of metal on samples.
