Thermogravimetric analysis (TGA) measurements were performed in a PerkinElmer Pyris Diamond TG/DTA analyzer (Waltham, MA, USA) under a protective nitrogen atmosphere. The temperature ranged from 50–500 °C with a heating rate of 2, 4, 6, 8, 10 °C/min, respectively. TG/IR analysis was performed with a TG/IR system, which combined with a PerkinElmer Pyris Diamond TG/DTA analyzer and a PerkinElmer Spectrum 100 FTIR spectrometer (Waltham, MA, USA). Samples of about 10 mg were pyrolysed in the TG analyzer and the evolved gases were led to the FTIR spectrometer directly through a connected heated gas line to obtain three dimensional FTIR spectra. The flow rate of N2 is 10 mL/min. The aluminum pans are used for the samples. The temperature of the heated transfer line is 200 °C. The heating rate for taking TGA/FTIR spectra is 10 °C /min. The operating conditions of the FTIR had a frequency range of 4000–400 cm−1, a resolution of 2.0 cm−1, and a scan rate of 1.0 scan/s.
Pyris diamond tg dta analyzer
Manufactured by PerkinElmer
Sourced in United States
The Pyris Diamond TG/DTA analyzer is a thermal analysis instrument that simultaneously measures a sample's weight change (thermogravimetry, TG) and thermal characteristics (differential thermal analysis, DTA) as a function of temperature or time under a controlled atmosphere. The instrument is capable of providing quantitative data on physical and chemical changes that occur in materials during heating or cooling.

For structural studies,
the diffraction peaks were characterized using an X-ray diffractometer
[Rigaku] at room temperature (Cu X-ray radiation of wavelength = 1.5406 Å and a scanning rate of
5°/min). X-ray photoelectron spectroscopy (XPS) was used to investigate
the presence of various oxidation states of the elements on the surface
of samples via a Thermo Fisher Scientific instrument (Escalab Xi+)
equipped with monochromatic Al Kα radiation. At a
heating rate of 10 °C/min, a PerkinElmer Pyris Diamond TG/DTA
analyzer was used to conduct a thermogravimetric analysis (TGA) from
room temperature up to 500 °C in air. In addition, the samples
were analyzed by Fourier transform infrared (FTIR) spectroscopy (Shimadzu,
IRSpirit-T, Japan) to determine their molecular composition. The surface
morphology and structural analyses of the samples were performed using
the field emission scanning electron microscope (FESEM: JEOL, JSM,
7600F) and transmission electron microscope (TEM: Talos F200X, Thermo
Fisher Scientific, USA). By utilizing Gatan and ImageJ software, the
images from the SEM and TEM were analyzed.

Characterization of the materials used in this study was performed by the following techniques: thermogravimetry and differential thermal analysis (TGA/DTA) in a PerkinElmer Pyris Diamond TG/DTA analyzer, with 10 ºC/min heating ramps, from 25 ºC to 600 ºC. Fourier transform infrared (FTIR) spectra were obtained in a Nicolet Nexus spectrometer (Thermo Fisher Scientific) equipped with a Smart Golden Gate attenuated total reflectance (ATR) accessory. Transmission electron microscopy (TEM) was carried out in a JEOL JEM 2100 instrument operated at 200 kV, equipped with a CCD camera (KeenView Camera). Phosphotungstic acid (PTA) was used to stain organic matter in the hybrid materials. N 2 adsorption was carried out on a Micromeritics ASAP 2010 instrument; surface area was obtained by applying the Brunauer-Emmett-Teller (BET) method to the isotherm and the pore size distribution was determined by the Barrett-Joyner-Halenda (BJH) method from the desorption branch of the isotherm. Mesopore diameter was obtained from the maximum of the pore size distribution curve. Z potential and hydrodynamic size of nanoparticles by Dynamic Light Scattering (DLS) were measured by means of a Zetasizer Nano ZS (Malvern Instruments) equipped with a 633 nm "red" laser.

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.
