新型介孔材料的热及水热稳定性OA北大核心CSCDCSTPCD
Thermal and Hydrothermal Stabilities of Novel Mesoporous Material
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.
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…查看全部>>
