A regular nanocrystalline supramolecular MgAl hydrotalcite was prepared via glycolfrequency microwavehydrothermal using MgCl2·6H2O
AlCl3·6H2O
Na2CO3 as raw material as precipitator. Hydrotalcite samples were characterized by Xray diffraction (XRD),scan electron microscope (SEM)
transmission electron microscope (TEM),IR
thermal analysis (TGDTA),and BETN2 surface area measurements. The images of SEM and TEM showed that the hydrotalcite exhibited as a homogeneous and hexagonal sheet. The XRD result indicated that the hydrotalcite was well crystallized. The influences of tradition hydrothermal
frequency microwavehydrothermal and glycolfrequency microwavehydrothermal on the sample character were investigated. A MgAl hydrotalcite with welldefined shape
obvious intercalated structure
well regular quality and welldispersing capability was obtained when glycol volume ratio was 10% at 120 ℃ for 5 h.
