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
