Synthesis of mono-dispersion mesoporous silica vesicles and spheres in 50–200 nm by using cationic-anionic binary surfactant as mesostructural template

The mesoporous silica vesicles and spheres with high surface area, large pore size and pore volume have been conveniently synthesized by using cationic-anionic binary surfactant system as template. The size of the mesoporous silica vesicles and sphere is uniform and ranged from 50–200 nm. In addition, these mesoporous silica nanoparticles possess the autofluoresce. The morphology and mesostructure are dependent on the pH value of the reaction solution.
