2.2 Characterization
The crystallinity of the MIL-120Al
powder was studied using a Bruker D8 ADVANCE X-ray diffractometer
employing Cu-Kα (λ = 1.5418 Å) radiation. Thermogravimetric analysis
(TGA) of the samples was performed on a Netzsch STA 449 F5 (Germany)
differential thermal analyzer under a nitrogen atmosphere. The
temperature test range was 298–1073 K and the heating rate was 10
K/min. Scanning electron microscopy (SEM) was performed on a ZEISS Sigma
300 at an accelerating voltage of 5 kV.
