Abstract

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
