在Pt/SiO_2多相催化剂上，H_2氧化和环己烯加氢反应中，Pt微晶的温度可以远高于SiO_2载体的温度。这种温度升高的程度取决于反应。催化剂颗粒上存在宽范围的温度，但这些温度在反应期间保持稳定。这些发现，通过红外发射光谱，获得的多相催化反应的动力学分析是重要的。
During H2oxidation and cyclohexene hydrogenationon Pt/SiO2heterogenous catalysts, the temperature of the Pt crystallite can be much higher than that of the SiO2support. 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.
