There has been great deal of interest in creating core-shell composite materials and hollow capsules with tailored structural, optical and surface properties using spherical nanoparticles as hosts. Various procedures have been applied to fabricate uniformly coated and stable colloidal particles. Monodisperse spherical solid core/ mesoporous shell (SCMS) silica particles were synthesized by adopting silica particles as core host components, surfactant molecules as structure-directing agents for the mesoporous shell and polymer molecules as additives for shell structure. Here, we reported three different types of mesoporous shell structure. The synthesis of uniform spherical silica particles with disordered, ordered and paralleled mesoporous shell was demonstrated by employing different structure-directing molecules for the formation of mesoporous shell.
