| Abstract: | Two kinds of mesoporous inorganic SiO2 (PW-P and PW-C) and two kinds of mesoporous phenyl-modified SiO2 (Ph-PW-C and Ph-PW-C-S) were prepared by aerosol-assisted self-assembly. Based on XRD, SEM, TEM and BET characterizations, the effects of the preparation conditions on the surface compositions, the surface morphology, the surface area, the pore volume, and the pore structure of the prepared samples were examined by changing the surfactant types, the silicate sources and the acidic/basic media used during the aerosol-assisted self-assembly. |
