MIL-100 (Cr), MIL-100
(Fe), MIL-101 (Cr), and aluminum fumarate (AlFu) MOFs were synthesized
according to previous literature.
30 (link)−33 (link) The details of the synthesis
are shown in the
Supporting Information (SI).
Powder X-ray diffraction patterns of the synthesized MOFs
were obtained by a PANalytical X’Pert Pro pw3040/60 diffractometer
with Cu Kα radiation operating at 45 kV and 40 mA. Brunauer–Emmett–Teller
(BET) surface area of the samples was collected on a Micromeritics
Tristar II at 77 K, and all samples were pretreated at 200 C for 15
h before measurement. Fourier transform infrared spectra (FTIR) of
powder samples was directly measured by a PerkinElmer Spotlight 400
FT-IR spectrometer with a range of 650–2500 cm
–1. The morphology and particle size of the samples were determined
by scanning electron microscopy (SEM, JEOL,
JSM-IT100). X-ray photoelectron
spectra (XPS) was collected using a ThermoFisher Al K-alpha apparatus
and scans were performed by a 400 μm spot size with an energy
step size of 0.2 eV. The thermal stability of four MOFs was investigated
by thermogravimetric analysis (TGA) using a Mettler-Toledo/STDA 851e
apparatus with a heating rate of 5 C/min.
