Abstract
The solvothermal method was utilized to synthesize the crystal of ZIF-8 by taking the molar ratio of the metal ions to the organic ligands of 2:1 at 120 °C. This was the best technological condition. Meanwhile, as demonstrated in characterization of the X-ray diffraction (XRD), scanning electron microscope (SEM), thermogravimetry (TGA) and Fourier Transform infrared spectroscopy (FTIR). SEM was showed that the crystal of ZIF-8 was endowed with high crystallinity and prismatic structure, with the size range of 5–10 μm, the BET specific surface area of the crystal was 739.4 m2 g−1. TGA was showed that its thermal stability could live up to 600 °C. FTIR was showed that the acid is completely protonated, and the Zn2+ and the 2-Methylimidazole are formed the crystal ZIF-8, in addition, O–Zn adsorption peak also existed in the crystal ZIF-8. Then the structure activity relationship of the crystal ZIF-8 synthesis, thermal stability and N2 sorption property was studied.
