英文摘要：

A regular nanocrystalline supramolecular Mg-AI hydrotalcite was assembled via glycol hydrothermal using MgCl2.6H2O、AlCl3.6H2O、Na2CO3 as starting materials and sodium hydroxide as precipitator. Hydrotalcite samples were characterized by XRD, SEM, TEM, IR, TG-DTA and BET-N2 surface area measurements and the influence of glycol- hydrothermal on characters of the sample was investigated. The Mg-A1 hydrotaleite with well-defined shape, obvious intercalated structure, well regular quality and well-dispersing capability can be obtained under the conditions at glycol volume ratio 15 %, hydrothermal temperature 180~ and reaction time 16h. The hydrotaleite obtained was well crystallized and had morphology of a homogeneous and hexagonal sheet, the thickness measured of each hexagon in the hydrotalcite was about 36 nm which was consistent with the value estimated by Seherrer equation.
