Powder X-ray diffraction (PXRD) analysis of powder samples was carried out on a PANalytical Empyrean Series 2 diffractometer with Cu Kα radiation ((λ = 1.540598 Å), which operated at 40 kV, 40 mA and a scan speed of 0.0167°, a scan time of 15 s per step and 2θ ranging from 5 to 60° at room temperature. The thermogravimetric analysis (TGA) data were obtained on a NETZSCH Thermogravimetric Analyzer (STA2500) from 25 to 800 °C with a heating rate of 20 °C min⁻¹ under an N₂ atmosphere. The contents of C, H, N, and S elements were determined by an Elementar Vario MICRO elemental analyzer with CHNS measurement mode. The SEM images were recorded on a Thermo Scientific Apreo 2C scanning electron microscope with an accelerated voltage of 10 kV. The Fourier transfer infrared spectroscopy (FT-IR) was tested by NICOLET FT-IR spectrometer (iS50 FI-IR), and the resolution was 4 cm⁻¹, the number of scans was 32, and the test wave number was 400–4000 cm⁻¹.

PXRD was collected on a PANalytical Empyrean Series 2 diffractometer with Cu Kα radiation (λ = 1.540598 Å), which operated at 40 kV, 40 mA, and a scan speed of 0.0167°, a scan time of 15 s per step, and 2θ ranging from 5 to 60° at room temperature. The thermogravimetric analysis (TGA) data were performed on a NETZSCH Thermogravimetric Analyzer (STA2500) from 25 to 800 °C with a heating rate of 10 °C/min under an N₂ atmosphere. The single-component adsorption isotherms of C₂H₂, CO₂, and C₂H₄ at 273, 298, and 323 K were measured on Micromeritics ASAP 2460 adsorption apparatus (Micromeritics Instruments, USA). The degassing procedure for all samples was carried out at 373 K under vacuum for 12 h before each adsorption measurement. The specific BET surface area was calculated based on the CO₂ adsorption isotherm data (0.05 and 0.15 relative pressure) at 195 K. The PSD was derived from the adsorption branch of CO₂ isotherms using the non-local density functional theory method and assuming a slit pore model.

Powder X-ray diffraction (XRD) patterns were collected using a PANalytical empyrean series2 diffractometer with Cu-Ka radiation, at room temperature, with a step size of 0.0167^°, a scan time of 15 s per step, and 2θ ranging from 5 to 50^°. The morphology was investigated using a NOVA 200 Nanolab scanning electron microscope (SEM). Fourier transform infrared (FTIR) spectra was recorded in the range of 400–4000 cm⁻¹ on a Nicolet 5700 FTIR spectrometer using KBr pellets. The thermogravimetric analysis (TGA) data were collected in a NETZSCH Thermogravimetric Analyzer (STA2500) from 25 to 700 °C with a heating rate of 10 °C/min. The CO₂ adsorption/desorption isotherms at 195 K were obtained on a Micromeritics ASAP 2460 volumetric adsorption apparatus. The apparent Langmuir-specific surface area was calculated using the adsorption branch with the relative pressure P/P₀ in the range of 0.005 to 0.1. The total pore volume (V_tot) was calculated based on the adsorbed amount of CO₂ at the P/P₀ of 0.99. The pore size distribution (PSD) was calculated using the H-K methodology with CO₂ adsorption isotherm data and assuming a slit pore model.

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.
