摘要：

Pt/KL contrasts with Pt/SiO2 in having: (1) a much greater selectivity for hexane aromatization; (2) a strong preference for cracking the terminal carbon-carbon bond as opposed to interior bonds. These properties, taken together, suggest enhanced terminal adsorption of the hexane molecule at the Pt surface. Pt/high-silica faujasite has similar characteristics. We believe the fact that Pt in both these zeolites is accessible only through portholes of ∼7.3 Å is a critical feature which leads to these unusual properties. © 1990.
