混合多孔固体(eg.MOFs,ZIFs)

混合多孔固体(e.g. MOFs, ZIFs) Several classes of new hybrid porous solids such as metal-organic framework materials (MOFs) , zeolitic imidazolate frameworks (ZIFs) as well as so-called covalent organic frameworks (COFs) have attracted a lot of attention during recent years. These novel nanomaterials are candidates for many applications due to their chemical versatility and distinctive adsorption properties. Potential applications range from catalysis, drug delivery, separation and gas storage. For instance, micro- and mesoporous MOFs show high adsorption capacities for CH4,CO2和H2在高压下。为了增加H的摄取2和CO2通过在环境压力下的物理吸附,用小的微孔吸附剂以及高比表面积和微孔体积是需要。微孔的MOF似乎更适合于通过物理吸附比介孔材料的气体混合物的分离。特别重要的是在流体吸附和“开放的金属位点”(配位不饱和的结合位点)之间的相互作用。尽管杂化多孔材料是结晶的样品中,各种因素可以向从完美的晶体结构的偏差。例如,减少的孔体积可以是由于在孔中的非易失性反应物,部分塌陷,和/或其它的激活相关的问题。Hence, an advanced physical adsorption characterization via (preferably) argon and nitrogen adsorption at their boiling tempertatures (e.g. 87 K and 77 K, respectively) is a key-technique and crucial for accurately assessing the effective pore sizes, pore size distribution, pore volumes and apparent surface areas of MOFs, ZIFs and COFs) . A full characterization of these materials with regard to gas storage and separation applications requires in addition to perform CO2,CH4和H2吸附实验在宽范围的压力和温度下(即子和超临界吸附)的。在各种温度下吸附实验允许一个也以获得吸附其可以与用于吸附位点中的MOF和其他杂化多孔材料吸附的有效亲和力(例如“打开金属位点”)相关联的等量吸附热。
