| 摘 要： | 采用室温固相反应结合水热处理制备了纳米层状双金属氢氧化物(LDHs)。利用X射线粉末衍射(XRD)、傅里叶变换红外光谱(FT-IR)、扫描电镜(SEM)、热重(TG-DTA)等分析方法对样品的物相、形貌、粒径、热稳定性进行了表征。研究结果表明经水热处理后,产品颗粒由不规则的团聚体转化为规则的六方形片状结构,改善了晶体结晶性能,生成了分散性良好的层状双金属氢氧化物。

| Abstract: | The nano-particle layered double hydroxides(LDHs) was synthesized by solid state reaction at room temperature and modified by means of hydrothermal method.The phase,morphology and particle size of the products were characterized by XRD,SEM,FT-IR and TG-DTA.The results showed that after hydrothermal treatment,products particles appear regular hexagonal plates structure which change from irregular aggregates,crystal structure become more stable and the dispersion properties of products are also improved.This ... |
