Abstract

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°C, hydrothermal treatment at low temperatures (400°C), and concentrations of steam (40 mol%), mechanical grinding and acid treatment (for 1 M HC1) but poor stability towards hydrothermal treatment with liquid water (even at 150°C) and base treatment, if it is dissolved in 0.1 M NaOH.
