摘要The dynamics feature of intercalation and assembly of B4O5(OH)(4)(2-) into layered double hydroxides intercalated by Cl- was investigated in this paper, based on the result of monitoring for viriation of solution concentration during the reaction course, and the results of EDS, IR, XRD, TEM and TG-DTA characterization for the samples produced from different reaction course. The results testified that the displacement of Cl- accorded with Stumm's kinetics pattern, the intercalation of B4O5(OH)(4)(2-) was controlled by diffusion course pattern. The investigation proved that the brucite layer structure and micropore structure feature of the precursor remained intact after ionic exchange, but the intercalation of bulky complicated B4O5(OH)(4)(2-) resulted in volume expansion of unit cell in c axial, increasing of micropore specific surface area, decreasing of grain size, and varying of thermodynamic action. The lattice parameter c aggrandized from 2.399 nm to 2.558 nm, the gallery height h aggrandized from 0.322 8 nm to 0.375 6 nm, with grain size decreasing of D. from 15.16 nm to 8.92 nm, D. from 10.93 nm to 4.55 nm, while specific surface area increased from 92.63 m(2)/g to 111.20 m(2)/g, and the thermodynamic action and TG-DTA characteristic was altered.
