Host-Guest Geometry in Pores of Zeolite ZSM-5 Spatially Resolved with Multiplex CAMS Spectromicroscopy

摘要

The geometrical arrangement of reagent molecules in the nanometer-sized pores of zeolite catalysts results from physicochemical interactions between reagent and catalyst, and plays a crucial role in determining the overall catalytic activity of the system. Steric constraints, for example, lead to favored molecular geometries and diffusion paths into and out of the pores, which, in turn, may influence the reaction pathway.
