Synthesis zeolitic Imidazolate Framework-8 (Zif-8) In Solvothermal: The Effect Comparison of Metal-Ligand

Abstract

Synthesis of ZIF-8 (zeolitic Imidazolate Frameworks-8) have been successfully carried out by the reaction of zinc nitrate and 2-methylimidazolate in DMF (N'N-dimethylformamide) solvent at a temperature of 120 °C for 24 hours. Synthesis of ZIF-8 has been conducted five times with variations molar ratio of metal (Zn2+):ligand (MeIM) consecutive 1:1; 1:1.5; 1:2; 1:2.5 and 1:3 to study the influence of metal-ligand ratio of the crystallinity and morphology of ZIF-8 that was produced. The results of characterization by X-ray diffraction, FTIR and SEM show that ZIF-8 is synthesized with a ratio of metal: ligand = 1:2 showed the highest crystallinity and has the most irregular surface morphology with form box.

Synthesis of Metal-Organic Frameworks Zinc (II) with Optimum Slow Pyrolysis Process for Conductivity Performance

“…MOFs exhibit advantages such as a large specific surface area, high gas storage and absorption capacity within their voluminous pores, and good conductivity properties [19]. Morphological and crystal size modifications of MOFs are crucial in synthesis methods as the shape and size of particles influence the functional properties of materials [20]. This study chose Zn for MOF synthesis due to its high gas absorption capacity, significant porosity, and suitability for further thermal treatment [21].…”
