Figure 4. Various synthesis methods for PET-derived MOFs and schematic representations of selected MOF structures (HKUST-1, ZIF-8, UiO-66, and MOF-5). The crystal structures were independently rendered by the authors using VESTA based on crystallographic data reported in the corresponding original publications: HKUST-1 (CSD Refcode: FIQCEN)[110], ZIF-8 (CSD Refcode: OFERUN)[111], UiO-66 (CSD Refcode: RUBTAK)[112], and MOF-5 (CSD Refcode: SAHYIK)[113], with crystallographic data obtained from the CSD[114]. CSD: Cambridge Structural Database; MOFs: metal-organic frameworks.
