Abstract :

New hybrid materials of exfoliated layered double hydroxide nanosheet (LDH NSs) and metal-organic frameworks (MOFs) were successfully synthesized. A colloidal suspension of LDH NSs was firstly prepared through hydrothermal reaction for powdery LDH (i.e., MgAl- NiAl-, and CoAl-LDH) and its exfoliation process in organic solvents (e.g. formamide and dimethylformamide). The MOF/LDH hybrid materials could be developed by the crystal growth of MOF in the colloidal suspension of LDH Ns. The obtained hybrid materials were systematically characterized by various tools such as powder XRD, SEM, TEM, BET, FT-IR, NMR, etc. The hybridization with layered inorganic nanosheets enhanced the structural stability of MOF, which is attributable due the strong coupling of MOF with functional groups on the surface of robust inorganic nanosheet. Gas adsorption and permeability test were carried out on hybrid materials and it was found that its performances were better than those shown by individuals. In addition, we tested photocatalytic ability of environmental remediation and water splitting. In this presentation, synthesis procedure and mechanism, structural formation, several applications for the hybrid materials will be discussed in detail. Obviously, the present study demonstrates the advantages of the hybridization with inorganic nanosheet not only in improving the structural stability of MOF but also in optimizing the functionality of this material.
