Figure 25. (A) Schematic representation of the synthesis of N-MIL@CNT and corresponding morphological characterizations. (B) Illustration of the synthetic route for the preparation of Pt single-atom coordinated ultra-thin MOF nanosheets (PtSA-MNSs) and corresponding morphological characterizations. (C) Schematic representation of the production of a core-shell type hybrid MOF (Fe-MIL-88B@Fe-MIL-88C) by anisotropic MOF-on-MOF growth, (C₁-C₉) SEM images of Fe-MIL-88B@Fe-MIL-88C during the formation process to monitor MOF-on-MOF growth. (D) Schematic representation of the proposed anisotropic MOF-on-MOF growth process from the tip to the middle. (A) Adapted with permission^[316]. Copyright 2020, American Chemical Society.
