Tóm tắt

In this work the experimental details and some examples of applications of diffuse reflectance infrared technique are described. Special interest has been devoted to a correct determination of the temperature of the sample, to gas-phase analysis, and to quantitative aspects in a DRIFTS controlled environmental cell. Applications to the analysis of the gas phase during catalytic hydrogenation and to the obtainment of kinetic parameters for the catalytic decomposition of adsorbates are included.
