Figure 2. (A) Diffusion patterns of three representative trajectories with a: immobile, b: hybrid and c: mobile motion types. (B) Spatial map of the distribution of trajectories with different motion types. (C) Schematic representation of the introduction of secondary pore networks into zeolites. (D) The fraction of each type of trajectory within the straight (orange) and sinusoidal (green) zeolite channels with secondary porosity (hatched bars), in comparison with the corresponding parent zeolite channels. (E) The effective diffusion coefficients for the straight (orange) and sinusoidal (green) zeolite channels with secondary porosity (hatched bars), in comparison with the corresponding parent zeolite channels.
