Abstract Magnesium‐ferrum layered double hydroxide (Mg‐Fe‐LDH) and zinic‐aluminum layered double hydroxide (Zn‐Al‐LDH) compounds were prepared through a mechanochemical method. The influence of molar ratio of M 2+ to M 3+ ( R value) on the property of LDH nanoparticles has been studied and the results showed that R =3:1 is the optimum value for the both samples. Besides pure water, the mixture of water and ethanol with the volume ratio of 3:1 is also used to wash the precipitates and used as suspending agent during the peptization process and our results showed that the addition of ethanol can improve the monodispersity of LDH nanoparticles greatly.
