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.
