| 摘 要： | 以Mn(NO3)2.6H2O、Zn(NO3)2.6H2O、Mg(NO3)2.6H2O和Al(NO3)3.9H2O为原料,采用水热合成法,一步合成了Mn-Zn-Mg-Al-CO3四元LDHs层状材料。采用ICP、元素分析仪、XRD、FTIR、TG-DSC、SEM、低温氮吸附-脱附等对样品进行了表征。探讨了pH值、反应温度、反应时间和原料配比对Mn-Zn-Mg-Al-CO3四元LDHs层状材料合成的影响。结果表明,在pH=10、反应温度控制在140℃、反应时间为24 h的条件下,可以合成出结构规整、晶形良好、各层间排列紧密有序的含不同比例金属阳离子的Mn-Zn-Mg-Al-CO3四元LDHs层状材料。其吸附等温线符合V型吸附,H3滞后环,晶体内层间存在2 nm以上的孔,晶体内部结构的有序性高,层间碳酸根离子的排列整齐,通道内孔密度大、孔径小、比表面积大。

| Abstract: | Regular Mn-Zn-Mg-Al-CO3 quaternary layered double hydroxides(LDHs) were synthesized by hydrothermal method in one step,using Mn(NO3)2·6H2O,Zn(NO3)2·6H2O,Mg(NO3)2·6H2O and Al(NO3)3·9H2O as raw materials.ICP,Elemental Analysis,XRD,IR,TG-DSC,SEM,low temperature nitrogen adsorption-desorption were used to characterize the composition,crystallinity,structure,morphology and performance of the obtained materials.The effects of pH value,reaction temperature,reaction time,molar ratio of raw materials on the structure of Mn-Zn-Mg-Al-CO3 quaternary LDHs were investigated.The results show that Mn-Zn-Mg-Al-CO3 quaternary LDHs with well-defined shape,obvious intercalated structure and well regular quality could be obtained at pH value about 10,the hydrothermal temperature of 140 ℃ and reaction time of 24 h.The nitrogen adsorption-desorption results suggest that the isothermal type of the sample is type V,hysteresis loop resembls the H3-type in the IUPAC classification.The samples have highly ordered intimate structure,neatly arranged interlayer anions,high hole density,small aperture and large surface area. |
