摘要	The dynamics feature and mechanism of preparation of layered double hydroxides pillared by Cl- anion (LDH-Cl) with coprecipitation reaction had been investigated, based on the result of monitoring concentrations during reaction course, and on the result of EDS, IR, XRD, TEM and TG-DTA characterization for samples produced from different reaction course. The results testified that the generating of LDH-Cl was controlled by polynuclcar layer surface reaction mechanism. It was also found that the lattice parameter c decreased from 2. 421 nm to 2. 399 nm, and h from 0. 3321 nm to 0. 3228 nm, with grain size increasing of D-a from 6. 40 nm to 15. 16 nm, D. from 7. 43 nm to 10. 93 nm, and increasing of aspect ratio from 0. 86 to 1. 39 during the whole reaction course, in addition, the strength of interaction between sheet and anions and the structure stability of sheet enhancing with reaction course as showed by IR and TG-DTA characterization.
