Abstract: A convenient direct decarbonation method was developed to prepare organically-modified layered double hydroxides using LDH-CO3 as raw material. The resulting products were characterized by powder X-ray diffraction(XRD), Fourier transform infrared spectroscopy(FTIR) and scanning electron microscopy(SEM). The results show that the LDH-DS and LDH-DBS with high crystallinity and high purity are successfully obtained, and their morphology and sizes are unchanged.

Key words: Layered double hydroxide(LDH), Organic anion intercalation, Direct decarbonation
