Abstract

This study proposes a fast and simple method for the growth of metal-organic frameworks (MOFs), Metal organic framework (MOF) membranes have attracted significant attentions in recent years. Zeolitic imidazolate frameworks (ZIFs), are a special kind of Metal organic frameworks (MOFs) that have been the subject of much research recently. Nanocrystalline Zeolitic imidazolate frameworks (ZIF-8), one of the most thoroughly researched metal-organic frameworks, was successfully produced via a solvothermal technique, using zinc nitrate as the metal precursor and 2-methylimidazole as the natural ligand. The synthesis involved two distinct organic solvents, namely dimethylformamide and methanol. The resulting ZIF-8 samples were characterized using X-ray diffraction (XRD) and Fourier-transform infrared spectroscopy (FT-IR), which confirmed the effective fabrication of extremely crystalline ZIF-8. The study also highlighted the importance of dissolvable choice in influencing ZIF-8 morphology. In conclusion, the solvothermal approach is illustrated to be a solid and cost-effective technique for the mix of extreme-quality ZIF-8.
