Stable and selective: γ-Al 2 O 3 nanosheets rich in pentacoordinate Al 3+ ions can well disperse and stabilize raft-like Pt-Sn clusters, which results in an increase of the electron density of the Pt sites. This material catalyzes the conversion of propane into propylene with >99 % selectivity, and minimizes coke formation and sintering processes.

The reaction pathways for the dehydrogenation of ethane, propane, and butane, over Pt are analyzed using density functional theory (DFT). Pt nanoparticles are represented by a tetrahedral Pt 4 cluster. The objectives of this work were to establish which step is rate limiting and which one controls the selectivity for forming alkenes as opposed to causing …
Pt–Sn/ZnAl 2 O 4 showed much better catalytic stability than Pt–Sn/Al 2 O 3. Pt–Sn alloys over Pt–Sn catalysts were unstable during the reaction. ...

the known effect of Sn on the dissociation of molecular H 2 on Pt-Sn surface alloys, we hypothesized that pairwise addition - a fundamental requirement for the observation of PHIP - should be strongly enhanced in Pt-Sn iNPs. The mSiO 2-protected Pt-Sn iNPs provide the first opportunity to test this hypothesis. We also

The Pt–Sn system is of high interest for a wide range of applications like soldering, specifically the interfacial reaction between the solder and the under-metallization for flip-chip assembly, see e.g. [1] or [2], heterogeneous catalysis (e.g. in [3], [4]), dentistry (e.g. in [5], [6]), jewelry (e.g. in [7]) to name just a few.As the Pt–Sn system is seldom …
3.1 PDH performance over the Pt–Sn/MgAl 2 O 4 catalysts. The 600-min PDH experiments for each catalyst were continuous without regeneration. As shown in Fig. 2, all Pt–Sn/MAS catalysts displayed an initial activity induction period in the first 50 min of the reaction, where both the propane conversion and propylene selectivity fluctuated.This …
