Inorganic Chemistry in Contemporary Research: Experiment on Metal-Organic Frameworks (MOFs)
Introduction

Metal-organic frameworks (MOFs) have emerged as a promising class of materials for a wide range of applications, including gas storage, separation, and catalysis. This experiment demonstrates the synthesis and characterization of a MOF-5, a well-known and well-studied MOF.


Materials

  • Zinc nitrate hexahydrate (Zn(NO3)2·6H2O)
  • 1,4-benzenedicarboxylic acid (H2BDC)
  • N,N-dimethylformamide (DMF)
  • Hydrochloric acid (HCl)
  • Sodium hydroxide (NaOH)

Procedure

  1. Dissolve 0.5 g of Zn(NO3)2·6H2O and 0.1 g of H2BDC in 50 ml of DMF.
  2. Add 1 ml of concentrated HCl to the solution.
  3. Seal the reaction vessel and heat it at 120 °C for 24 hours.
  4. Cool the reaction mixture to room temperature and centrifuge it to collect the MOF-5 crystals.
  5. Wash the crystals with DMF and then with water.
  6. Dry the crystals under vacuum.

Characterization

The synthesized MOF-5 crystals were characterized using a variety of techniques, including:



  • Powder X-ray diffraction (PXRD) to determine the crystal structure.
  • Scanning electron microscopy (SEM) to observe the morphology of the crystals.
  • Nitrogen adsorption/desorption isotherms to measure the gas sorption properties.

Significance

This experiment demonstrates the synthesis and characterization of a MOF-5, a versatile material with potential applications in gas storage, separation, and catalysis. The experiment provides hands-on experience with the synthesis and characterization of inorganic materials, and it highlights the importance of inorganic chemistry in contemporary research.
