Abstract

Methods of Surface Organometallic Chemistry (SOC) were used to prepare new type of supported Sn-Pt catalysts. In the new approach the focus was laid on the stabilization of tin in the form of SnOx anchored directly to the platinum. The new surface species have been characterized by different methods. The results indicate the platinum nano-clusters are decorated by SnOx surface entities with Lewis-acid character. The new Sn-Pt/Al2O3 catalysts were tested in hydrocarbon reactions above 500 C. Due to the presence of new acid sites in the atomic closeness to the platinum the new Sn-Pt catalysts showed decreased aromatization and increased isomerization selectivities.
