A large quantity of MgAl-layered double hydroxide (LDH) nanoparticle was successfully obtained from a single batch from high concentration (as high as 1 M) of metal salts solution. LDH were obtained by the precipitation at room temperature under ambient pressure and subsequent aging. The phase purity, crystallinity, anion composition, and morphology (shape and size of the LDH crystals) were investigated to characterize the products. Chloride type MgAl LDH with well-defined platy shapes of the lateral size of 50 nm was obtained with the very high efficiency (approximately 10 g from the 160 mL of the starting solution).
