Synthesis and characterization of methyl-orange/layered double hydroxide (LDH) nanocomposite
首发时间:2011-01-11
Abstract:In this paper, the intercalation of methyl-orange (MO) into Mg/Al (ratio=2:1) layered double hydroxide (LDH) was carried out using reconstruction method to obtain MOLDH nanocomposite material. Its chemical composition, crystal structure, appearance and thermal stability were characterized by XRD, FT-IR, TEM, TG-DTA and element analysis. It has been found that the MOLDH still keeps the typical lamellar structure, and the guest MO has been intercalated into the layers of the host LDH. The MOLDH's disassembly temperature is higher more than 30 C than that of guest molecule MO, so it can be used as a new dye with high thermal stability.

甲基橙/LDH纳米复合材料的合成与表征研究
摘要:本文利用再构法将甲基橙插层到Mg/Al(摩尔比=2:1)的层状双氢氧化物(LDH)中得到MOLDH纳米复合材料。并利用XRD、FT-IR、TEM、TG-DTA和元素分析对它的化学组成、晶体结构、形貌和热稳定性进行了表征,发现客体MO被插层到主体LDH之后所形成的MOLDH仍然具有典型的层状结构。MOLDH的分解温度比客体分子MO高过30℃,因此有望作为一种新型的耐高温染料。
