  • Figure 1. ZIF-8 where Zn2+ is coordinated to 2-methylimidazole ligands through N atoms
  • Figure 2. Three examples of ZIF-8 synthesized by the solvothermal method using DMF as solvent. The crystals with rhombic dodecahedron morphology are shown in a square with a yellow border
  • Figure 3. Powder XRD pattern of ZIF-8. The peaks were indexed with the appropriate Miller planes by using the CIF of ZIF-8 and the Mercury software, as mentioned in the text. The insert shows the pattern generated by Mercury from the CIF of ZIF-8, for comparison with the experimental powder XRD pattern
  • Figure 4. Crystal structure of ZIF-8 viewed along the a axis, and showing an unit cell (parallelogram with sides in red, blue and black colors). For clarity, the hydrogen atoms are not shown. The orange, violet and grey spheres represent the zinc, nitrogen and carbon atoms. Drawn by using the CIF of ZIF-8 and the Mercury software
  • Figure 5. FTIR spectrum of ZIF-8
  • Figure 6. TG analysis of ZIF-8: 14.336 mg of sample in a platinum crucible; temperature range 50-700°C; heating rate 10°C min−1; under argon flow at 20 mL min−1. The weight loss of 56.6 wt% occurring between about 300 and 610°C is given
