摘要:
以Cu(NO3)2·3H2O 、Ni(NO3)2·6H2O和Al(NO3)3·9H2O为原材料,Na2CO3-NaHCO3为缓冲溶液,Na2CO3 为沉淀剂,采用水热法制备了优质的CuNiLDH. 研究结果表明:当水热反应温度为180 ℃、反应时间为120 h时制得的CuNiLDH晶体最优.用X-射线衍射(XRD)、透射电镜(TEM)、N2比表面吸附、元素分析和热失重分析对制备的样品进行了表征.计算得出CuNiLDH晶胞参数a=0.30 4 nm,c=2.402 nm,h=0.324 nm.推导出CuNiLDH的化学式为Cu1.3Ni2.2Al(OH)8CO3·4H2O.讨论了缓冲对在CuNiLDH晶体生长过程中的作用.
Abstract:
High quality CuNiLDH is prepared by hydrothermal method using Cu(NO3)2·3H2O,Ni(NO3)2·6H2O and Al(NO3)3·9H2O as raw materials,mixture of Na2CO3 and NaHCO3 as buffer solution and Na2CO3 as precipitant.Through test,the results show that the optimal reaction temperature is 180 ℃ and the reaction time is 120 h.The samples are characterized by X-ray diffraction(XRD),transmission electron microscopy(TEM),N2 specific surface adsorption,elemental analysis and thermogravimetric analysis.The cell parameters of CuNiLDH are calculated and a=0.304 nm,c=2.402 nm,h=0.324 nm are given.The formula of CuNiLDH is Cu1.3Ni2.2Al(OH)8CO3·4H2O.The effect of buffer pair on the growth of CuNiLDH crystal is also discussed.
