摘要/Abstract

摘要：

以柠檬酸为成孔剂, 正硅酸乙酯为硅源, 硫酸铝为铝源, 在水热条件下合成一种新型介孔硅铝材料, 并采用X射线衍射（XRD）和透射电镜（TEM）对样品进行表征. N₂吸附脱附结果表明, 新型介孔材料在1 173 K的高温条件下焙烧5 h以及在沸水中分别处理48,96,192,288 h后, 样品依然保持较好的介孔结构, 表明样品具有较好的热及水热稳定性.

关键词: 介孔材料；热稳定性；水热稳定性

Abstract:

A novel mesoporous aluminosilicate material was synthesized with citric acid as pore forming agent, tetraethoxysilane (TEOS) and

Al₂(SO₄)₃·18H₂O as silica source and aluminum source, respectively. The sample was characterized by XRD and TEM. The results of N₂ adsorptiondesorption showed that the mesoporous structure of novel material was maintained under the condition of both calcinations at 1 173 K in air for 5 h and treatment in the boiling water for 48,96,192 and 288 h.

Key words: mesoporous material, thermal stability, hydrothermal stability
