金属有机骨架（MOF）材料中的配合不饱和金属位具有有趣的化学性质，可作为单位点催化剂应用。在这里，我们报告了最近的进展，为mof内部发生的化学反应提供了基本的见解。除了常见的粉末形式外，我们还讨论了MOF薄膜（SURMOFs）的潜力。将光谱和建模相结合的方法应用于选定的体系，表明mof的催化活性可以精确调节。一个特别有趣的例子是所谓的缺陷工程，其中结构缺陷以受控的方式产生。MOF材料的化学性质可以通过整合和修饰连接剂或加载客体物质（如金属或金属氧化物纳米粒子或纳米团簇）来进一步修饰。层接层方法制备MOF薄膜的一个特别有趣的方面是实现串联催化剂的前景。图形抽象
AbstractIsolated, coordinatively unsaturated metal sites within metal–organic framework (MOF) materials feature interesting chemical properties and offer applications as single-site catalysts. Here, we report on the recent progress in providing fundamental insight into chemical reactions occurring inside MOFs. In addition to the common form, powders, we discuss the potential of MOF thin films (SURMOFs). The combined spectroscopic and modeling approach applied to selected systems demonstrated that the catalytic activity of MOFs can be precisely tuned. A particular interesting case is the so-called defect-engineering, where structural imperfections are created in a controlled fashion. The chemical properties of MOF materials can be further modified by integration and decoration of linkers or loading with guest species, such as metal or metal–oxide nanoparticles or nanoclusters. A particularly interesting aspect of layer-by-layer approaches for the fabrication of MOF thin films is the prospect to realize tandem catalysts.Graphical Abstract
