Chemisorption of H 2 S on Al 2 O 3 supported platinum is dissociative and hydrogen is observed in the gaseous phase. Above 100°C, platinum surface atoms are fully covered by sulfur atoms. Hydrogen treatment at 400°C partly restores the catalytic an

The evolution of the relative concentration of CO bridged species with the NiCu alloys composition allows to estimate the copper efficiency to inhibit this kind of chemisorption. This efficiency decreases as the copper content increases. One coppe

UV and visible reflectance spectra of Pd(II) ion exchanged zeolites have been recorded before and after hydrogen reduction. The reduction was performed either at 25°C (60% reduction) or at 500°C. Reoxidation by oxygen at 400°C restored the initial

Ni(II) ions in different zeolites have been reduced by hydrogen or carbon monoxide under mild conditions. In some cases Ni(I) ions appeared, whose concentration was related to the crystal field strength. By desorption at high temperatures Ni(I) ions
