| 摘 要： | 本文以ＫＮＯ３，Ｎｉ（ＮＯ３）２，ＴｉＯ２为原料，通过固相反应，制备出高结晶度Ｋ－Ｎｉ－Ｔｉ层状金属氧化物（简称“ＬＭＯ”），并详细考察了制备条件，筛选出最佳合成条件。经ＸＲＤ，ＳＥＭ，ＴＧ－ＤＴＡ及ＢＥＴ表征，初步探讨了Ｋ－Ｎｉ－ＴｉＬＭＯ的基本性能，说明该ＬＭＯ具有较高的热稳定性。同时，ＨＡＣ，ＮＨ４Ｃｌ，正己铵的引入，使ＬＭＯ的网面间距由０．７８ｕｍ分别增加到０．８６ｎｍ，０．８８ｎｍ和２．３３ｎｍ．

| Abstract: | K-Ni-Ti layered metal oxide (K-Ni-TiLMO) with high crystallinity is successfully prepared through a solid-state reaction of the mixture of KNO3,Ni (NO3)2 and TiO2. Moreover, the optimum preparation conditions is. obtained by investigating the effects of the reactant rations, reaction temperature and time on crystallinity of products in details. The products are also characterized by XRD.SEM, TG-DTA and BET techniques. It is shown that K-Ni-Ti LMO possesses high thermal stability. Introduction of acetic acid, ammonium chloride and hexylamine by ion exchange increases its interlayer distances (d values) from 0.78 nm to 0.86 nm, 0.88 nmand 2.33 nm, respectively. |
