摘　　要：通过水热合成法,制备了系列层状镁铝双氢氧化物纳米片,并对产物的阴离子插层性能进行了研究和分析.使用X射线衍射仪(XRD)、扫描电子显微镜(SEM)等手段对所得样品进行结构检测.结果表明,所得产物为直径约5μm,厚度约20nm的六方纳米片.不同阴离子的层间插入对双氢氧化物颗粒形貌有较大影响,层间距随阴离子链长减小而减小:LDH-SDBS>LDH-NO_3^->LDH-S_2O_3^(2-).Mg/Al layered double hydroxides（LDHs）with nanosized morphology were synthesized by hydrothermal method.The obtained particles and anions intercalation were also characterized by X-ray diffraction（XRD）and scanning electron microscopy（SEM）.The results showed that the obtained particles are hexagonal with mean diameter of 5μm and depth of 20 nm,and the morphology of particles are unsteady after various anions intercalation,and the layer space is decreasing after intercalation by shorter anions chains：LDH-SDBS 〉 LDH-NO3-〉 LDH-S2O32-.
