A new method for preparation of nanoplates of Zn-Al layered double hydroxides
Source abstract
Abstract
Abstract Methods for preparation of nanoplates of layered double hydroxides (LDHs) have been intensively investigated for the purpose of making nanocomposites. The present study provides a new simple method of nanoplate preparation for Zn-Al LDHs. Zn-Al LDHs containing lactate or combinations of lactate and simple inorganic anions were synthesized by a coprecipitation method, and water-washed and undried LDHs were dispersed in water. Among them, suspensions of Zn-Al LDHs containing both lactate and bicarbonate were unique in that they rapidly became translucent colloidal dispersions when the molar ratio of added bicarbonate to added Al was ≤ 0.5. The resulting LDH nanoplates in the dispersions were delaminated single layers or nanoplates with a thickness of several layers, depending on the amount of bicarbonate.
