The capabilities of XPS to study heterogeneous catalysts are severely restricted for supported Pt/MgAlOx catalysts. When XPS spectra from these catalysts are taken with the standard AlKα or MgKα irradiations, the Pt4f doublet line is masked by a strong Al2p line as well as by the additive lines-satellites from Mg2s line. A possible solution of this problem could be the use of AgLα irradiation with the photon energy of 2984.3 eV for excitation of Pt3d5/2 and Al1s lines. AgLa irradiation is an useful tool for investigation of supported Pt-alumina catalysts. The values of Pt3d5/2 binding energy can be used for determination of the oxidation state of platinum in supported Pt/MgAlOx catalysts and other systems containing both platinum and aluminum.
