Distribution of crystalline/amorphous phases with the (MIL-53)0.25(agZIF-62)0.75 CGC. a Contour plots of in situ synchrotron powder diffraction data measured during the thermal treatment process of (MIL-53)(ZIF-62)(25/75) (10 °C min−1). The Bragg peak hkl indices are marked for ZIF-62, MIL-53-as and MIL-53-lp. b Three-dimensional tomography and the corresponding STEM-EDS mapping of (MIL-53)0.25(agZIF-62)0.75 CGC. White arrows highlight the region of Al in both 2D and their corresponding 3D images. Scale bar is 400 nm. c Scanning electron diffraction (SED) mapping and the corresponding STEM-EDS mapping of the composite glass. Scale bar is 200 nm
