然而,到目前为止多孔金属-有机骨架一直限制在微孔范围,其较小的孔道不利于物质扩散和传输,从而限制其实际应用。
However, to date porous MOFs are still largely restricted to the microporous regime despite negative impact of their small pore size on diffusion and mass transfer for their practical applications.
介孔允许大分子进入孔道同时具有较小的扩散限制,微孔则作为小分子的吸附场所,使小分子能够很好的择型催化。
The mesoscale pores are benefit to the diffusion of larger molecules with low resistance, while the micro-scale pores can provide effective catalytic sites of small molecules with high selectivity.
刚性烧结微孔管由于有一定的壁厚,毛细孔道的深层也可起明显的过滤作用。
Because rigid sintered microporous tube have certain wall thickness, and the deepness of pores can also have apparent filtering effect.
