Metal-organic frameworks (MOFs) are a class of distinctive porous crystalline materials constructed by metal ions/clusters and organic linkers. Owing to their structural diversity, functional adjustability, high surface area, different types MOF-based single sites well exploited, including coordinately unsaturated from nodes metallolinkers, as active species immobilized MOFs. Furthermore, controllable thermal transformation MOFs can upgrade them nanomaterials functionalized with single-atom catalysts (SACs). These unique features derivatives enable serve highly versatile platform for catalysis, which has actually been becoming rapidly developing interdisciplinary research area. In this review, we overview the recent developments catalysis at in emphasis on structures applications thermocatalysis, electrocatalysis, photocatalysis.

In this perspective we summarize advantages limitations fundamental issues to be addressed about their applications. MOF framework compositions pore can strongly influence performance, allowing, for example, shape-selective bifunctional catalysis, research needed quantify reaction/transport processes identify sites, determine intrinsic reaction rates. Progress hindered lack understanding heterogeneity sometimes being such defects not determined X-ray diffraction crystallography.
