On the role of promoters in hydrogenations on metals; α,β-unsaturated aldehydes and ketones
TL;DR: In this paper, the authors suggest a model of surfaces active in selective hydrogenation of unsaturated aldehydes, based on the information available in the literature on the adsorptions through the C-C and C-O groups, together with the information on the catalytic behaviour of the promoter-free and promoted catalysts.

State of tin in Pt-Sn/Al2O3 reforming catalysts investigated by TPR and chemisorption
TL;DR: In this article, the state of tin in Pt-Sn Al 2 O 3 was investigated by temperature-programmed reduction (TPR) and adsorption of H2 and of O2.

Propane dehydrogenation on PtSn/ZSM-5 catalyst: Effect of tin as a promoter
TL;DR: In this article, a PtSn/ZSM-5 catalyst with different amounts of Sn was prepared for propane dehydrogenation and it was found that the addition of Sn not only had a geometric effect, but also changed the interfacial character between metal and support.

A study of the 119Sn mössbauer isomer shifts in some platinum-tin and gold-tin alloys
TL;DR: In this article, the 119Sn isomer shifts at room temperature in some Pt-Sn and Au-Sn alloys have been measured and attributed to the lower number of valence s-electrons per atom for platinum compared to that for gold.

Activation of hydrogen on Fe/MgO catalysts studied by magnetic methods and mössbauer spectroscopy
TL;DR: In this paper, two activation processes of H2 were observed, at room temperature and above 470 K, according to the reversible redox scheme Fen+ + nHadsFe+ nH+, with n probably equal to 2.
