The hollow silica sphere (HSS) is a particle. This particle has specific interior space that can be used in various fields such as catalysis, waste removal, adsorption, storage, and controlled release of chemicals. Most of HSS synthetic researches focus on micelle states in order to get appropriate hollow structures and sizes. In this study, we synthesized homogeneous HSS by using sol-gel reaction with cetyltrimethylammonium bromide (CTAB) micelles containing tetraethoxysilane (TEOS). We could control particle sizes containing hollow structures by varying temperature, reaction time and ammonia concentration. We confirmed their structures and sizes by scanning electron microscope (SEM), transmission electron microscopy (TEM), Dynamic light scattering (DLS), and so on. |
