Preparation of Layered Double Hydroxides Nanomaterails via the Anionic Surfactant

Different Mg-Al layered double hydroxide (LDH) nanomaterials had been synthesized using anion surfactant in the solution of mixed solvents. Using sodium dodecylbenzenesulfonate (SDBS) as morphology-controlling agent, different morphologies of Mg-Al LDHs are obtained successfully. The concentration of the reactant and the dosage of SDBS had significant effects on the morphology of the products. The morphologies of flower-like spheres, nanospheres, and micro-particles were efficiently obtained, respectively. X-ray powder diffraction (XRD) and scanning electron microscopy (SEM) were used to characterize these products.
