Hollow sphere silica(HSS) materialhave been extensively studied such as drug delivery system, catalyst, and display because of their extraordinary structure. Nano-sized HSS material were synthesized by a sol-gel method applying cationic surfactant CTACl in basic condition and nonionic surfactant pluronic F-68 in acidic condition, respectively.HSS samples were characterized by TEM and N2-sorption. Diameter of HSS, which was prepared by CTACl,is about 250 nm and surface area is about 1000 m2/g, but diameter of HSS, which was prepared by F-68,is about 30 nm and surface area is about 500 m2/g. |
