In Situ XRD Analysis of Li2O2 Formation

XRD measurements
were taken using a PANalytical X’Pert Pro PW3040/60 diffractometer
with Cu Kα radiation operating at 45 kV and 40 mA in a 2θ
range of 31–65°. Scans (each ∼30 min in duration)
were recorded for the batteries during a complete (dis)charge cycle
with a current density of 0.3 mA/cm2. Refinement of the
diffraction data was performed using the Rietveld method as implemented
in the FullProf program. To more accurately fit the zero position
(effectively positioned at a different height in the cathode) of the
Li2O2 diffraction pattern, peaks arising from
the current collector as well as carbon paper were excluded from the
fits.

Synthesis and Characterization of Metal-Organic Frameworks

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.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
