Size control and optimisation of intercalated layered double hydroxides

Two types of organo-layered double hydroxides (LDH), with adipate or dodecyl sulfate in the interlayer space, have been prepared by the coprecipitation. In order to improve the homogeneity and to obtain well crystallised solids, the samples were submitted to microwave (MW) irradiation. Hydrotalcite (HT)-like compounds were obtained in all cases. The TEM and particle size distribution point out that even short irradiation times led to homogeneous and well defined solids with small particle size.
