金属-有机骨架（MOF）配位聚合物的产生使得能够定制具有从微米到纳米孔尺度的规则孔隙率的新型固体。自从发现这个新的纳米多孔材料家族和所谓的“网状设计”概念以来，现在已知数百种不同类型的MOF。作为配位中心的金属离子与各种多原子有机桥接配体连接在一起的自组装导致可定制的纳米多孔主体材料作为具有高热和机械稳定性的坚固固体。将给出不同含锌结构的描述实例，例如MOF-2、MOF-5和IRMOF 8验证的合成方法，以及一种全新的过渡金属基MOFs电化学测试方法，在现有样品的基础上，以催化和气体处理领域中的金属有机骨架材料为例进行了测试。报告了炔的催化活化（由丙炔形成甲氧基丙烯，由乙炔合成乙烯基酯）。天然气中杂质的去除（甲烷中痕量的四氢噻吩）、稀有气体（氪和氙）的变压分离和氢的储存（在Cu-BTC-MOF上在2.0 MPa/77 K下为3.3重量%）将强调金属有机框架在气体处理中的未来工业用途。在可能的情况下，与最先进的应用进行比较，以概述使用MOF可能具有上级的可能性。
The generation of metal-organic framework (MOF) coordination polymers enables the tailoring of novel solids with regular porosity from the micro to nanopore scale. Since the discovery of this new family of nanoporous materials and the concept of so called 'reticular design', nowadays several hundred different types of MOF are known. The self assembly of metal ions, which act as coordination centres, linked together with a variety of polyatomic organic bridging ligands, results in tailorable nanoporous host materials as robust solids with high thermal and mechanical stability.Describing examples of different zinc-containing structures, e.g. MOF-2, MOF-5 and IRMOF8 verified synthesis methods will be given, as well as a totally novel electrochemical approach for transition metal based MOFs will be presented for the first time.With sufficient amounts of sample now being available, the testing of metal-organic frameworks in fields of catalysis and gas processing is exemplified. Report is given on the catalytic activation of alkynes (formation of methoxypropene from propyne, vinylester synthesis from acetylene). Removal of impurities in natural gas (traces of tetrahydrothiophene in methane), pressure swing separation of rare gases (krypton and xenon) and storage of hydrogen (3.3 wt% at 2.0 MPa/77 K on Cu-BTC-MOF) will underline the prospective future industrial use of metal-organic frameworks in gas processing. Whenever possible, comparison is made to state-of-art applications in order to outline possibilities which might be superior by using MOFs.
