摘要：
Influence of various thermal, hydrothermal and acid/base treatments on the structural stability of highly siliceous MCM-41 mesoporous material has been thoroughly investigated. It has good stability towards thermal treatment up to 650 degrees C, hydrothermal treatment at low temperatures(less than or equal to 400 degrees C), and concentrations of steam (less than or equal to 40 mol%), mechanical grinding and acid treatment (for 1 M HCl) but poor stability towards hydrothermal treatment with liquid water (even at 150 degrees C) and base treatment, if it is dissolved in 0.1 M NaOH.
