| Abstract | In recent years, the synthesis, crystalline structure, and applications of zeolite imidazole frameworks (ZIFs) have attracted extensive attention. Since the ZIF L phase was synthesized, a new phase was observed during the heating process, but its crystal structure is unknown. The unknown new phase, which was named ZIF L300 in this study, was confirmed again. In this study, the X ray powder diffraction technique and Rietveld refinement were used to solve the crystalline structure of the unknown ZIF L300 phase. The results demonstrate that ZIF L300 has the same chemical formula (ZnC8N4H10) as in ZIF 8 and belongs to a hexagonal structure with a space group of P61. The lattice parameters have been determined as follows: a = b = 8.708(7) angstrom, c = 24.195(19) angstrom, alpha = beta = 90 degrees, and gamma = 120 degrees. The X ray absorption fine structure (XAFS) technique was also used to extract the local atomic structures. The in situ X ray diffraction (XRD) technique was used to monitor the structural evolution of the as prepared ZIF L in a temperature range from room temperature to 600 degrees C. The results show that the sample experiences a change process from the initial ZIF L orthorhombic phase (<210 degrees C), to the ZIF L300 hexagonal phase (similar to 300 degrees C), then to an amorphous phase (similar to 390 degrees C), and finally to a zincite ZnO phase (>420 degrees C). These sorts of structural information are helpful to the application of ZIF materials and enrich the knowledge of the thermal stability of ZIF materials. |
