Résumé
The surface patterning of mesoporous silica nanotubes was observed in the mesoporous materials hydrothermally synthesized under mild-alkaline conditions in the presence of cetylpyridinium surfactants. Direct hydrothermal synthesis in an ammoniated solution or posthydrothermal treatment of room-temperature- synthesized materials were performed alternatively. The formation mechanisms were investigated. It is revealed that the roles of ammonia during direct-or post-hydrothermal treatment are different.
