Fig. 3: TEM/SAED analysis of MOFs heated at 300 °C for 5 h.

a–c BF-TEM images of 5%NH2-MIL as an overview (a) and of an individual MOF particle (b) along with the corresponding SAED pattern (c). d–f and g–i show the corresponding BF TEM and SAED data for the 10% and 50%NH2-MIL, respectively. All SAED patterns have been indexed using the cif file and fit the MIL-125-Ti structure,30 viewed along the [001] zone axis. No indications of other phases were detected in the SAED data.
