Synthesis of Nonspherical Banana-Like Mesoporous Silica and their Vertically Deposition Assembly

Abstract:

Nonspherical mesoporous silica with banana-like morphology has been synthesized successfully through organic-inorganic cooperative interaction by adding the small molecules additives. SEM and TEM image revealed that the silica with banana-like morphology possess hexagonal pore channels and packed parallel to the long axis. XRD further confirmed the high ordered two dimensional (2-D) hexagonal (p6m) mesostructure. N2 adsorption-desorption measurement show that they have high BET surface area and large pore size and pore volume. Impressively, through vertical deposition assembly technique, the anisotropic nonspherical banana-like mesoporous silica can be organized into closely-packed monolayer and multilayer film, demonstrating potential application in photonics, electronics and magnetics.
