Structure‐Activity Relationships in Highly Active Platinum‐Tin MFI‐type Zeolite Catalysts for Propane Dehydrogenation

Abstract

Abstract Pt/Sn‐containing MFI zeolites prepared by one‐pot hydrothermal methods are highly active and selective catalysts for propane dehydrogenation. An alternative preparation method is reported alongside an in‐depth characterization of Pt and Sn before and after reaction. Pt species dispersed on highly‐defective Silicalite‐1 show a significantly long catalytic lifetime with an improved coke resistance, but increased Pt−Sn alloying and the (eventual) build‐up of carbon leads to deactivation.
