Synthesis and characterization of a 2-periodic cadmium-based metal-organic framework: A study on reversible water adsorption

Year: 2022

Type: article

Abstract: A previously - reported cadmium-based two-periodic metal-organic framework [Cd 1.5 (BTC)(H 2 O) 4.5 ] n · n H 2 O ( CP1 ) has been re-synthesized, where H 3 BTC = 1,3,5-benzenetricarboxylic acid. CP1 was characterized with single crystal X-ray diffraction (SCXRD), powder X-ray diffraction (PXRD) followed by various thermal analyses such as thermogravimetric analysis (TGA), hot stage microscopy (HSM) and differential scanning calorimetry (DSC). CP1 is composed of 2-periodic layers, which are interdigitated. Heating can effectively remove the uncoordinated and coordinated water molecules resulting in an amorphous product CP1′ . The original framework can be regenerated by readsorption of water from the atmosphere, indicating that the dehydration is reversible.
