| Outline of Final Research Achievements |
Separation and collection of rare metal ions from industrial wastes are important to establish stable supply of rare metal ions. Size controlled monodisperse colloidal mesoporous silica nanoparticles (CMS) with functional groups should enable to separate and collect multiple rare metal ions concurrently. Therefore, to separate and collect multiple rare metal ions concurrently from solution containing various kinds of metal ions, we mainly focused on precise preparation of CMS with high controllability of particle size and functionality. We succeeded in preparation of size controlled CMS with high monodispersity enough to be fabricated as colloidal crystals. In addition, CMS with various hydrophobic functional groups were prepared. Furthermore, it was revealed that addition of phenyltriethoxysilane lead to the formation of unique Janus structured CMS.
