摘　　要：采用水热法制成了镁铝碳酸盐型、镁铝硝酸盐型、镁铝盐酸盐型、镁铝羟基型等插层镁铝类水滑石,比较了层间含不同阴离子类水滑石的结构差异和高温热处理后的结构稳定性。通过离子交换方式以镁铝羟基型为基材插层组装无机阴离子基团MoO42-、WO42-、CO32-和NO3-制得不同的阴离子插层类水滑石。通过XRD、TEM、XPS和热分析方法对镁铝类水滑石和阴离子插层类水滑石进行了表征。Several Mg-Al hydrotalcite-like compounds containing various anions were synthesized via coprecipitation-hydrothermal-treatment.Their structure differences and thermal stability were studied.Using them as raw materials,the hydrotalcite-like compounds insetted MoO42-、WO42-、CO32-andNO3-ions were synthesized via anion exchange.XRD,XPS,thermal analysis and TEM were used to characterize them.
