| titleOfInvention | A kind of preparation method of multistage mesoporous silica nano-particle |
| abstract | The invention discloses a kind of preparation method of multistage mesoporous silica nano-particle, the method use long-chain ion liquid surfactant as template, organic molecule amine be alkali source, tetraalkyl silicon ester is silicon source, deionized water is for water source is as raw material; Raw material mole consist of silicon source: ionic liquid surfactant: organic molecule amine: water=1:0.01 ~ 0.3:0.001 ~ 8.0:40 ~ 1000.Grain diameter prepared by the present invention can realize Effective Regulation within the scope of 20 ~ 200nm, the mesoporous SiO of synthesisn 2 nanosphere size is homogeneous, specific surface area ~ 1000mn 2 / g, pore volume ~ 2.0ml/g, between the 2 ~ 30nm of aperture, and have obvious divergent shape pore passage structure from inside to outside, i.e. so-called multistage meso-hole structure.Synthetic method of the present invention is simple, easily mass-producing, the cycle is short, cost is low, reproducible, be a kind of eco-friendly synthesis strategy. |
