摘要: 报道了一种制备多元金属柱撑粘土的新方法——生长法.将此法与通用的同晶取代法制得的样品进行比较,发现前者的镍含量远大于后者.此种交联物的底面间距约1.7nm,样品在IR谱中744cm-1处出现的吸收谱带可作为柱状物存在的标识,插入层间的柱状物中镍以六配位形式存在,是一种类尖晶石结构,处于这种状态的镍要比同晶取代进入Johansson离子中的镍更难于被还原.

Abstract: Multi-metal pillared clay was prepared wih a new method—growth.The amountof nickel in the framework obtained from the said method was far more than that from the substitution.The layered spacing of the product was about 1.7 nm.The band of 744 cm-1 on IRspectrum of sample may be a criterion for proving the presence of the pillar.The nickel ion in the pillar existed in a hexadentate form.The structure of the pillar was similar to the spinel.The nickel ion in this state was reduced more difficultly than that in Johansson ion.

Key words: that in Jojansson ion.Pillared clay, Nickel, Growth
