WebJan 5, 2008 · The actual PSD accounts for both intracrystalline and intercrystalline void spaces. The DFT pore size distribution for three MOF-5 shown in Fig. 3 changes from more complex to less complex and more uniform pore structures from MOF-5(α) to MOF-5(β) and to MOF-5(γ), suggesting better crystallinity generates more uniform PSD in the MOF-5.
