Abstract

We report herein the adsorption of light hydrocarbons in small crystal ZSM-5 monitored by infrared spectroscopy including a direct monitoring of the individual concentrations (surface and intracrystalline). Accessing the individual rates reveals that the sorption enhancement upon surface modification with TEOS is selective towards molecules with a small steric demand and a high heat of adsorption within the silica overlayer. Graphical Abstract: [Figure not available: see fulltext.]
