【摘要】 首次报道了通过室温固相法,合成纳米层状双金属氢氧化物(简称LDH)。考察了反应物配比、反应时间分别对试样物相的影响。采用X-射线衍射仪(XRD)、透射电镜(TEM)分别对样品的物相、形貌、粒径等进行了表征。结果表明,反应物配比、反应时间对产物物相有很大影响,镁铝比为3 1,反应时间控制在60min制备的样品分散性好,晶型单一,粒子呈针状,长120nm,宽20nm。更多还原

【Abstract】 The nanoparticle layered Double Hydroxides(LDH) was synthesized by solid state reaction at indoor temperature.The products were characterized by XRD,TEM,IR and element analysis.The experimental result indicates,that the sample takes the form of needle,wide 10nm,about long 80nm.The method is a general,inexpensive and effection approach based on solid state reaction to synthesized nano-layered double hydroxides with uniform size and shape in high yields.The mechanism was studied primarily.更多还原
