This paper provides a general overview of the phenomenon of guest diffusion in nanoporous materials. It introduces the different types of diffusion measurement that can be performed under both equilibrium and non-equilibrium conditions in either single- or multicomponent systems. In the technological application of nanoporous materials for mass separation and catalytic conversion diffusion often has a significant impact on the overall rate of the process and is quite commonly rate controlling. Diffusion enhancement is therefore often a major goal in the manufacture of catalysts and adsorbents.

纳米孔中的扩散：检查地面

本文提供了纳米多孔材料中客体扩散现象的一般概述。它介绍了可以在单组分或多组分系统中的平衡和非平衡条件下执行的不同类型的扩散测量。在用于质量分离和催化转化扩散的纳米多孔材料的技术应用中，通常对工艺的总速率具有重大影响，并且通常是速率控制。因此，扩散促进通常是催化剂和吸附剂制造中的主要目标。
