Figure 4

The theoretical values for diffusivities of gas storage in the pmg-MOF-5.

a, The illustration presenting diffusions at the interface of micropores and meso/macropores, which was determined through theoretical calculations. b, Calculation results that show diffusivities for diffuse-in, diffuse-out and lattice diffusion. The diffuse-in is for gas migration from micropores to meso/macropores while diffuse-out is for one from meso/macropores to micropores.
