Pt–Sn alloy phases and coke mobility over Pt–Sn/Al2O3 and Pt–Sn…

Propane dehydrogenation on Pt–Sn/Al 2 O 3 and Pt–Sn/ZnAl 2 O 4 was performed, and the Pt–Sn/ZnAl 2 O 4 catalyst showed a stronger tolerance for catalytic deactivation than the Pt–Sn/Al 2 O 3 catalyst. In this study, we propose that the high catalytic stability of Pt–Sn/ZnAl 2 O 4 originates from the relatively faster coke mobility from the metal …

Preparation of highly dispersed Pt–Sn/Al2O3 catalysts via …

An increase in the Sn/Pt ratio will further reduce the particle size of Pt and increase its dispersion. When the Sn/Pt ratio is 1.5, it shows the best catalytic activity. The metal particle size of the catalyst has a great influence on the dehydrogenation process of methylcyclopentane (MCP), showing an obvious size effect.

At room temperature, the corresponding rate outstrips the activity of Pt(111) by several orders of magnitude. According to the oxidation pathways, the activation barriers are actually lower on Pt 3 Sn(111) and Pt 3 Sn/Pt(111) surfaces than on Pt(111). A generalization of Hammer's model is proposed to elucidate the key role of tin on the ...

Pt–Sn bimetallic nanoparticles (BMNPs) are used in a variety of catalytic reactions and are widely accepted as a model system for Pt-based bimetallics in fundamental catalysis research. Here, Pt–Sn BMNPs were prepared via a two-step synthesis procedure combining atomic layer deposition (ALD) and temperature programmed reduction (TPR).

Synthesis of Bimetallic Pt/Sn-based Nanoparticles in Ionic Liquids

Abstract. We demonstrate a method for the synthesis of bimetallic nanoparticles consisting of Pt and Sn. A synthesis strategy is used in which the particular physico-chemical properties of ionic liquids (ILs) are exploited to control both nucleation and growth processes. The nanoparticles form colloidal sols of very high colloidal stability in ...
