文摘

Mesoporous silica nanotubes with coiled pore channels in the walls were prepared using the self-assemblies of a gelator as template previously. The TEM images were simulated using Autodesk 3D studio MAX 9.0 here. These hierarchical nanotubes were organized into μm-size balls by increasing the concentration of gelator and controlling stirring speed. Bimodal pore structure was identified by a N₂ adsorption method.
