In this study, we introduced a solvent-free mechanochemical route to synthesize Li-Al layered double hydroxide through a two-step grinding of LiOH and Al(OH)3, in which the mixture powder with Li/Al molar ratio at 1/2 was first dry ground for 2h and then wet ground for another 1h with water addition without any heating operation. The as-prepared samples were characterized by X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FT-IR), thermogravimetry (TG), differential scanning calorimetry (DSC) and scanning electron microscopy (SEM). The products possessed highly crystalline of Li-Al LDH phase with no evident impure phases, presenting an easy and effective preparation of Li-Al LDH by using solvent-free mechanochemical approach.
