| titleOfInvention | A kind of method of preparing mesoporous silicon dioxide micro-sphere |
| abstract | The invention discloses a kind of method of preparing mesoporous silicon dioxide micro-sphere, the method is to add nonionic surface active agent in temperature is the cushioning liquid that is 5 to pH value under the condition of 25～40 DEG C, after nonionic surface active agent dissolves completely, add again anionic surfactant, treat that solution becomes colorless transparent, add afterwards anhydrous sodium sulfate and stir, after stirring, adding tetramethoxy-silicane again and being stirred to solution is milky, hydrothermal crystallizing after leaving standstill, the white precipitate that hydrothermal crystallizing is obtained passes through washing, vacuum drying and calcining successively. Synthesizing mesoporous silicon dioxide microsphere method of the present invention is that preparation possesses the duct that high-sequential is arranged in the gentle system of pH=5, continuously the meso-porous titanium dioxide silicon particle of adjustable, aperture homogeneous. By ratio, the ionic strength of cushioning liquid etc. of reconciliation statement surface-active agent, the aperture of material is adjustable continuously between 5-18nm. |
