During H 2 oxidation and cyclohexene hydrogenation on Pt/SiO 2 heterogenous catalysts, the temperature of the Pt crystallite can be much higher than that of the SiO 2 support. The extent of this temperature rise depends on the reaction. There is a wide range of temperatures on the catalyst particles, but these temperatures remain stable during the reaction. These findings, obtained by IR emission spectroscopy, are of importance for the kinetic analysis of heterogeneously catalyzed reactions.
