| Abstract: |
| Mesoporous materials are extensively applied as catalysts and their supports,adsorbents and separate mediums etc.owing to the characteristics of high specific surface area,pore size uniformity and ordered pore structure. This paper introduce the structural characteristics of block copolymers and their self-assembled behaviors in a selective solvent.With block copolymers as templating agent,the preparation of mesoporous materials with high specific surface area and high thermal stability by sol-gel methods are summarized,which includes the controlled processing,affecting factors and the technical characteristics of preparing non-silicon mesoporous materials. |
