中文摘要：

层状双氢氧化物（Layered double hydroxide,LDH）是一种具有阴离子可交换性质的层状无机材料,由于其具有多种功能性质,已被广泛应用于催化[1～3]、酸吸附剂[4]、传感器[5]及聚合物填料[6～8]等领域.传统的共沉淀法制备的LDH结晶度低、尺寸小（直径通常小于100 nm）.1998年,Costantino等[9]采用均匀沉淀法制备出了高结晶度、大尺寸（微米量级）且层间具有CO2-3的LDH（LDH-CO3）,引起了人们的极大兴趣.

英文摘要：

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-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.
