In this work we used several complementary techniques (TEM, TPR, CO chemisorption, EXAFS and FTIR spectroscopy) to understand the effects of the activation temperature and activation atmosphere (air or H2) on the particle size distribution, the fract

The vibrational properties of adsorbed carbonyls on heterogeneous Pd/oxide systems (SiO2−Al2O3, Al2O3, and MgO) are compared and discussed. On the basis of the surface science literature, the complex IR spectra of carbonyls formed on Pd particles a

Four different methods for Pd dispersion measurement are compared: H2adsorption, O2adsorption, H2titration, and O2titration. A correct comparison requires the knowledge of H/Pdsand O/Pdsstoichiometries. The H/Pdsstoichiometry is discussed by reviewin

The deactivation of a silver catalyst was investigated after six years of industrial production of ethylene oxide. Temperature-programmed reduction was used to characterize the chemical nature of the silver and its reactivity towards oxygen. The fres
