直接脱碳酸化制备有机离子插层的层状双氢氧化物

摘要

A convenient direct decarbonation method was developed to prepare organically-modified layered double hydroxides [ dodecyl sulfate or dodecyl benzene sulfonate anions intercalated LDHs(LDH-DS or LDH-DBS) ] using LDH-COj 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.
