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.

Effect of Promotion with Sn on Supported Pt Catalysts for CO2Reforming of CH4
TL;DR: In this article, the authors investigated the catalysts of CH4 with CO2 and showed that the Pt/ZrO2 catalyst had much higher activity and stability than the Pt and SiO2-supported Pt-SiO2 catalysts due to its ability to promote CO2 dissociation.

Comparative study of propane dehydrogenation over V-, Cr-, and Pt-based catalysts: Time on-stream behavior and origins of deactivation
TL;DR: In this article, the authors compared the catalytic performance of VO x /MCM-41 possessing highly dispersed VO x species in non-oxidative propane dehydrogenation (DH) was compared with that of industrially relevant catalysts such as CrO x/MCM41 and Pt-Sn/Al 2 O 3 over four DH (24h on-stream) and oxidative regeneration cycles and the effect of reduction with H 2 on the catalysts DH properties.

Extended X-ray absorption fine structure studies of platinum-tin catalysts
TL;DR: Extended X-ray absorption fine structure (EXAFS) studies at 140 K, along with studies of Xray absorption edges themselves, were conducted on a Pt-Sn/Al/sub 2/O/sub 3/ catalysts that had previously been exposed to hydrogen at high temperatures.

Studies of Pt-Sn/Al2O3 catalysts prepared by Pt and Sn coevaporation (solvated metal atom dispersion)
Yong-Xi Li,Kenneth J. Klabunde +1 more
TL;DR: In this paper, it was shown that Sn{sup 0} within and on Pt particles has a significant effect on catalyst performance, and suggest that such performance can be predictably modified by using the correct preparation procedure (SMAD or conventional).
