Skeleton nanoparticles and method for manufacturing the same |
| abstract |
Skeleton nanoparticles and method of forming the same. The skeleton nanoparticles comprise silica shells. Each of the silica shells has a shape of a cubic frame formed of six faces as a whole. The cubic frame is hollow inside and pores are formed between quadrilateral silica frames on respective faces of the cubic frame. The method comprising: coating an organic acid on surfaces of calcium carbonate particles; dispersing the organic acid-coated calcium carbonate particles in an organic solvent that dissolves a part of the organic acid in the organic acid-coated calcium carbonate particles, and further mixing a silicon alkoxide and a base catalyst to form silica-forming particles by forming the silica shell along an edge of the calcium carbonate particles; and dissolving the calcium carbonate at an inside of the silica-forming particles by an acid treatment. |
