一种层状双金属氢氧化物LDH-Br-I-(NO3-)2晶须及其制备方法和应用
摘要：
本发明涉及一种层状双金属氢氧化物LDH‑Br‑I‑(NO3‑)2晶须及其制备方法和应用。所述晶须的化学式为Mg6Al2（OH）14BrI（NO3）2·4H2O；所述晶须通过金属阳离子Mg2+和Al3+与阴离子Br‑、I‑、NO3‑和OH‑反应得沉淀后蒸发水分得到。本发明提供的层状双金属氢氧化物LDH‑Br‑I‑(NO3‑)2晶须为一种晶须状的类水滑石化合物除具有孔径的可调变性、较大的比表面积和层间离子可交换性等类滑石类化合物的功能外，还具有晶须增韧补强的功能，在增韧补强材料，催化、阻燃、吸附材料等领域中具有非常广泛的应用前景。本发明提供的制备方法，工艺简单，适合大规模推广。
摘要（英）：

The invention relates to a layered bimetallic hydroxide LDH-Br-I-(NO3-)2 whisker as well as a preparation method and application thereof. The chemical formula of the whisker is Mg6Al2(OH)14BrI(NO3)2.4H2O. The preparation method of the whisker comprises the following steps: reacting metallic cations including Mg<2+> and Al<3+> with anions which include Br<->, I<->, NO<3-> and OH<-> to obtain a precipitate, then evaporating water to obtain the whisker. The layered bimetallic hydroxide LDH-Br-I-(NO3-)2 whisker is a whisker-shaped hydrotalcite-like compound, has the functions of adjustable hole diameter, large specific surface area and exchangeable interlayer ions of the hydrotalcite-like compound, also has the functions of toughening and reinforcing the whisker, and has extremely extensive application prospects in the fields of toughening and reinforcing materials, catalysis materials, flame-retardant materials, adsorption materials, and the like; the preparation method is suitable for large-scale popularization with a simple process.
