Abstract
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 post-hydrothermal. 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.
