A facile mechanochemical approach to synthesize Zn-Al layered double hydroxide

摘要

In this study, a mechanochemical route to synthesize Zn-Al layered double hydroxide (LDH) was introduced, in which Zn basic carbonate and Al hydroxide were first dry milled into an activated state and then agitated in water to obtain the final products. The as-prepared samples were characterized by X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FT-IR), Thermogravimetry (TG) and Scanning electron microscopy (SEM). The products possessed a high crystallinity of Zn-Al LDH phase without any other impurities, proving a facile and effective preparation of Zn-Al LDH by using non-heating mechanochemical approach.
