Preparation method for nanosheet of uniformly dispersed layered double hydroxides (LDHs)

The present invention belongs to the technical field of nano material prepared, were directed to a method for preparing nano-dispersed hydrotalcite single piece, first soluble inorganic M2 + Y divalent and trivalent inorganic salts M3 + Y arranged mixed and dissolved in deionized water a salt solution, and then an alkali solution prepared using conventional techniques, the use of microchannel reactors enables mixed salt solution and alkali solution and reacted to obtain hydrotalcite sufficiently washed with deionized water, obtained after centrifugation (LDHs) a precipitate comprising gum nanosheet monolayer, i.e. monodispersed hydrotalcite nano monolithic; its preparation process is simple, mild preparation conditions, low cost, environmentally friendly production, a wide range of product applications, high economic value.
