Fourier transform infrared spectroscopy (FTIR) was carried out on the sample using IRPrestige-21 Fourier transform infrared spectrometer (Shimadzu Corporation, Kyoto, Japan), the scanning range was 400~4000 cm−1, the resolution was 4 cm−1, and the number of scans was 32 times.
Irprestige 21 fourier transform infrared spectrometer
Manufactured by Shimadzu
Sourced in Japan
The IRPrestige-21 Fourier transform infrared spectrometer is a laboratory instrument manufactured by Shimadzu Corporation. It is designed to perform infrared spectroscopy analysis by measuring the absorption or transmission of infrared radiation through a sample. The instrument uses a Michelson interferometer to generate the infrared beam and a Fourier transform algorithm to analyze the signal.

X-ray diffraction (XRD) patterns were obtained from a powder X-ray diffractometer (D8 Advance, Bruker AXS GmbH, Karlsruhe, Germany) with Cu Ka radiation (l = 0.154056 nm). Scanning electron microscopy (SEM) images were received from a scanning electron microscope (EVO10, ZEISS, Jena, Germany) operated at an acceleration voltage of 20.0 kV. Raman spectra were performed on a LabRAM Aramis Raman spectrometer (HORIBA Jobin Yvon, Paris, France). Transmission electron microscope (TEM) images were recorded with a transmission electron microscope (JEOL JEM-2100, Tokyo, Japan). X-ray photoelectron spectroscopy (XPS) was obtained on a Thermo Electron ESCALAB250 XPS Spectrometer (X-ray Source: Al). Fourier transform infrared spectroscopy (FTIR) spectra were recorded on an IRPrestige-21 Fourier transform infrared spectrometer (Shimadzu Corp., Kyoto, Japan). A traditional three-electrode system (unmodified or modified GCE (id = 3.0 mm)) was used as the working electrode, platinum wire as the counter electrode and saturated calomel electrode (SCE) as the reference electrode for all electrochemical tests. Second derivative linear sweep voltammetry (SDLSV) was performed on a JP-303E polarographic analyzer (Chengdu instrument factory, Chengdu, China).

We have
used SEM to characterize the morphological features of all samples
by employing a FEG-SEM MIRA 3 (Tescan, Czech Republic). Due to the
high electrical conductivity of the samples, no previous metal-sputtering
treatment was necessary (except for the pure ESM, where a fine gold
layer was deposited). Raman spectra were obtained in the 800–2000
cm–1 region by using a microscopic confocal Raman
spectrometer (LabRAM Aramis; HORIBA Jobin Yvon, France), with a 633
nm He–Ne laser. The electrochemical testing of the prototype
symmetric SCs was carried in a two-electrode configuration. The devices
were mounted in a Solartron 12962A sample holder between two carbon
cloth electrodes. All electrochemical (cyclic voltammetry, galvanostatic
CD, and electrochemical impedance) measurements were carried out at
room temperature using Autolab PGSTAT302N (Metrohm, Switzerland).
FTIR measurements were performed using the KBr method in IR Prestige-21
Fourier Transform Infra-Red Spectrometer (Shimadzu, Japan).

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.
