A mechanochemical approach to get stunningly uniform particles of magnesium-aluminum-layered double hydroxides

► A mechanochemical approach is developed to get uniform and monodispersed LDHs. ► This approach includes two processes, i.e., grinding and peptization process. ► Peptization plays a critical role in the formation of high crystallinity hexagons. ► The size and morphologies of LDHs can be precisely controlled.
