Synthesis and Growth Mechanism of the HTlc-glutamate
摘要
Abstract
A hexagonal HTIc-glutamate was assembled via glycol-hydrothermal using MgCl2 · 6H2O, A1Cl3 · 6H2O, glutamic acid as raw material and sodium hydroxide as precipitator. Samples were characterized by X-ray diffraction ( XRD ) , scan electron microscope ( SEM) , IR, thennal analysis ( TG DTA) and BET-N2 surface area measurements. The result indicated that HTIc-glutamate exhibited well-defined shape and obvious intercalated structure during the glycol-hydrothermal process. From the point of the model of anion coordination polyhedron growth units, the growth mechanism and morphology of the HTIc-glutamate was also studied. The result indicated that the growth morphology of HTIc-glutamate was consistent with the model. The HTIc-glutamate growth process included ① growth units incorporated to metal layers first,② metal layers adsorbed glutamate and H2O, ③ growth units incorporated to layer compounds according. As a result, glycol played important role in bridging.关键词
