Abstract

Nanoporous materials are employed in numerous technologies of matter upgrading by mass separation and conversion (heterogeneous catalysis). The chapter deals with the measurement of guest diffusion in such materials and, thus, with the determination of a key parameter for performance enhancement of these technologies. The introduction of two “microscopic” measuring techniques (PFG NMR and microimaging), which are the focus of this chapter, gave rise to a paradigm shift in our understanding of mass transfer in such materials. Nanoporous host–guest systems are, moreover, shown to serve as an ideal model system for investigating spreading phenomena quite in general. Ample options of investigation range from the comparison of equilibrium and non-equilibrium phenomena towards the investigation of conversions of both the spreading individuals and their environment.
