Studies On Designing, Assembling And Structures Of Rare Earths Functional Materials With Supramolecular Structures

Rare earths have been the object of considerable scientific and technological interest due to their distinctive optical, electronic, and magnetic properties. Layered double hydroxides (LDHs), also referred to as hydrotalcite-like compounds, are a family of important lamellar inorganic functional materials and have enormous potentiality in such aspects as catalysis, ion-exchange, absorption and the luminescence, electricity and magnetism. In this paper we combined the structural advantages of LDHs and excellent performance of rare earths by assembling Eu3+ into the interlayers and layers of LDHs, separately.First [EuEDTA]- complex was prepared and intercalated into MgAl-NO3 LDHs precursor by ion-exchange method. XRD, IR, ICP and TG-DTA were used for characterization. XRD structure parameters showed that after intercalation the gallery heights of LDHs increased a lot,...
