Application Peculiarities Of In Situ Xps And Mass Spectrometry Methods To Study Concentration Hysteresis In Methane Oxidation Over Alumoplatinum Catalysts

Concentration hysteresis in methane oxidation over alumoplatinum catalysts was studied by in situ XPS and mass spectrometry. It was determined that the activation of catalysts was accompanied by partial reduction of platinum the boundaries of existence of concentration hysteresis and effect on them of the particle size of the active component were defined.
