摘要：

In this article, glutamic acid (Glu) was intercalated into the Zn-Al layered double hydroxides (Zn-Al LDHs) by hydrothermal method. The influence of the molar ratio of Zn/Al/Glu (R values for short), the aging time, and the pH value of the washing solution was systematically studied. The resulting Glu-LDH compounds were characterized by x-ray diffraction (XRD), fourier transform infrared spectroscopy (FTIR), and scanning electron micrograph (SEM). The XRD results showed that the relative diffraction intensity first increased then decreased as the R value and the pH value of the washing solution increased. Moreover, the crystallinity degree decreased gradually with the increase of the aging time. The absorption peaks attributed to the stretch of (R-COO-) were observed in the FTIR spectra. SEM graphs indicated that the morphology of the particles was largely influenced by the synthesis conditions.
