【Abstract】 Hydrotalcite-type compounds, including hydrotalcite(HT) and hydrotalcite-like compounds(HTLCs), are anionic clay minerals. The structures of hydrotalcite-like compounds are described. The methods of preparation of hydrotalcite-type compounds and pillared HTLCs are summarized. The analysis methods, such as XRD, IR, Raman, Solid MAS-NMR, ESR and thermal analysis employed to characterize the pillared HTLCs, are introduced. The applications of pillared HTLCs, are reviewed and prospected.更多还原
