| 英文摘要 | by grafting amines onto the mesoporous support sba-15, a highly efficient adsorbent has been obtamed. this material shows potential applications in the removal of co2 from enclosed areas such as space shuttles and submarines. sba-15 was modified with 3-aminopropyl-triethoxysilane (aptes) by post-synthesis silylation and one-step silylation methods using ethanol as the solvent. the physical properties of these adsorbents were characterized by x-ray powder diffraction and n-2 adsorption- desorption. the ordered hexagonal mesoporous structure of sba-15 is well preserved after the modification. co2 adsorption was tested using a static adsorption equipment. adsorption isotherms demonstrate that the one-step silylation method is better than the post-synthesis silylation method. sba-15 that was modified with aptes through one-step sitylation can adsorb 34. 2 mg/g of co2 at room temperature when the partial pressure of co2 is 0. 005 mpa. active carbon, the traditional adsorbent of co2 was also tested. at room temperature, modified sba-15 shows better performance than active carbon when the partial pressure of co2 is lower than 0.02 mpa. |
