中文摘要: 本项目旨在设计合成热稳定性优良,包含有微孔、介孔和大孔的MOF型多级孔材料。为了确保所设计合成的多级孔材料的稳定性,研究着眼的MOF是目前已经发现的热稳定性最好的微孔MOF;应用恰当的合成手段,借助于模板剂的作用,使得所获得MOF包含有微孔(小于2nm),介孔(5-50nm)和大孔(大于60 nm)的多级孔材料。这样的多级孔材料一方面克服了通常应用纤细配体所形成的MOF无法达到无机介孔材料孔径的难题,同时在经过有目的性的修饰后使得其介孔和大孔成为加强对特定吸附质吸附功能进行化修饰的空间,从而可以实现该类多级孔材料在多方面的应用:诸如某些气体和液体分子的选择性吸附分离,药物分子的吸附分离,蛋白大分子的吸附分离,催化剂乃至生物酶大分子的担载等。

英文摘要: This project is going to design and syntheze a series of thermal stable MOFs with the porosity ordered at all length scales. In order to make sure that the hierachical porous materials obtained have enough higher thermal stability, we choose the most stable MOFs discovered so-far in the world for realizing the purpose. By using suitable synthetic strategies and with the help of some templates, the hierachical materials with their micropores from the basic MOFs (< 2 nm), meso-pores sized (5-50 nm) and macropores (over 60 nm) could be obtained. Moreover, such hierachical porous materials based on MOFs ordered at all length scale can be then decorated with their meso- and macropores for different adsorbants of some gaseous or liguid molecules, drug, protein molecules or some catalysts and enzymes with which supported for applications in the chemical catalysis.
