WebFeb 17, 2024 · Figure S1 exhibits the DFT pore size distributions of ZIF-8 and amine@ZIF-8 materials. Apparently, for each MA-ZIF-8, MMEN-ZIF-8, and ED-ZIF-8 material, the main pore size was lower than that of the as-made ZIF-8. Figure 3 demonstrates the DFT pore size distributions for the best amine@ZIF-8 materials. WebAug 22, 2024 · The pore size distribution (PSD) is an important characteristic of microporous materials with pore sizes of less than 2 nm because it is related to the transport of molecules, which is correlated to …
