Mesoporous materials because of its large specific surface area and adsorption capacity, so in the field of adsorption, separation and catalysis have a wide range of applications. In this paper, the use of cetyl trimethyl ammonium bromide (CTAB) as a template, sol-gel synthesis of mesoporous silicon dioxide nanoparticles by transmission electron microscopy (TEM) and N2 adsorption characterization methods for the synthesis of mesoporous structure and properties of silica analyzed, discussed different tetramethoxysilane (TMOS), particle size CTAB amount of mesoporous silica nanoparticles, specific surface area and pore size.

The performance of silane coupling agent on the silicon dioxide powder particles, the shape presents small spherical particles, while the silicon dioxide sample is amorphous matter; the SiO2/PEG fusion occurs much increased thick.

With the rapid development of modern science and technology, especially the development of nanotechnology, microscopic material ordered its different specificities can cause people's attention. Many researchers into this field. Ordered in a variety of materials, ordered porous materials have made great progress. It has long been recognized that a porous material, has long been the use of it is light, porous characteristics of the porous material is used as a structural material, adsorbent material, carrier material and barrier material, and many other aspects.
