摘要： 层间距为1.44 nm层状氢氧化苯甲酸锌在乙醇、正丙醇、正丁醇介质中可剥离成其基本组成单元纳米层. 用TG-DTA、XRD、SEM、TEM和元素分析等手段研究了剥离的纳米层重组得到样品的结构特征、形貌和化学组成. 结果表明: 水热合成样品和剥离的纳米层重组样品具有相同的层状结构, 它们的化学组成分别为Zn(OH)1.12(C6H5COO)0.88和Zn(OH)1.1(C6H5COO)0.9. 水热合成的纤维状粒子剥离重组后改变成为像纳米带和纳米花粒子形貌.

Abstract: The exfoliation reaction and recombination of the layered hydroxide zinc benzoate compound with a fibrous particle morphology and a basal spacing of 1.44 nm in ethanol, n-propanol and n-butanol were researched. The characteristic, particle morphology and chemical composition of the sample recombined by exfoliated nano-sheets were investigated by using XRD, TG-DTA, SEM, TEM and elementary analysis. The results indicated that the samples obtained by hydrothermal synthesis and recombinated by exfoliated nano-sheets in alcohol solvents have the same layered structures, and their chemical formulas can be written as Zn(OH)1.12(C6H5COO)0.88 and Zn(OH)1.1(C6H5COO)0.9, respectively. The 1.44 nm layered phase can be exfoliated in ethanol, n-propanol and n-butanol solvents, and the exfoliated nano-sheets can be recombined into nano-belt-like and nano-flower-like particles.

Key words: Layered compound, Hydroxide zinc benzoate, Exfoliation, Recombination of nano-sheets
