摘要： 在110～180 ℃范围内, 以Zn(OH)2与苯甲酸为原料水热法成功合成了层状氢氧化苯甲酸锌化合物. 通过XRD、TG-DTA、SEM、TEM和元素分析研究了合成产物的结构、形貌、性质和化学组成, 探讨了合成条件对水热反应产物的影响. 当C6H5COOH/Zn的摩尔比为0.9～1.0, 水热温度130～150 ℃及水热反应12 h, 合成的层状化合物具有纤维状粒子特征, 层间距为1.44 nm, 化学组成为Zn(OH)1.12•(C6H5COO)0.88.

Abstract: Layered zinc benzoate hydroxide compound with a basal spacing of 1.44 nm was prepared by hydrothermal reaction in a temperature range of 110～180 ℃. XRD, TG-DTA, SEM, TEM, and elementary analysis were used to characterize the structure, particle morphology, characteristic, and chemical composition of the synthesized layered compounds. Meanwhile, the effect of the synthetic conditions on the obtained compound was also investigated. The results indicated that when the molar ratio of C6H5COOH/Zn was 0.9～1.0, the temperature 130～150 ℃ and the reaction time 12 h, the prepared compound was of fibrous particle morphology, and its chemical formula can be written as Zn(OH)1.12•(C6H5COO)0.88.

Key words: Layered compound, Zinc benzoate hydroxide, Hydrothermal Synthesis
