| 发明名称 | Method for preparing rod-like silica fine particles including carbon | ||
| 摘要 | Disclosed is a method for preparing rod-like silica fine particles including carbon, the method including: a first step of preparing a mixed solvent by mixing a surfactant with alcohol, and then preparing a mixed solution by adding water, ethanol, ammonia water and a salt to the mixed solvent; a second step of forming rod-like silica fine particles by adding a silica precursor to the mixed solution; and a third step of carbonizing the rod-like silica fine particles, and through a sol-gel reaction of the silica precursor and a carbonization process thereof. | ||
