Metal-organic frameworks (MOFs) are porous polymers categorized by metal clusters (also known as SBUs) coordinated with organic ligands, resulting in one-, two-, or three-dimensional structures. The organic ligands involved are occasionally denoted as 'struts' or 'linkers', an instance being 1,4-benzenedicarboxylic acid (BDC).

Characteristics:

High porosity

Large specific surface area

Structural diversity

Applications:

Catalysis: The pores of MOFs are composed of metal centers and organic linkers, offering versatility in composition and structure through a wide array of metal nodes and potentially limitless organic linker options. The metal nodes of MOFs can purposefully select catalytically active metal elements to construct different types of catalytic materials.

Hydrogen storage: Adsorption occurs when atoms or molecules are captured upon contacting a surface, hence the adsorption capacity of a material correlates with its surface area. In a three-dimensional scenario, the greatest surface area is achieved through a highly porous structure, allowing atoms and molecules to reach internal surfaces. This straightforward qualitative reasoning indicates that highly porous metal-organic frameworks (MOFs) hold great promise as candidates for hydrogen storage devices.

Gas separation: Using computational high throughput screening, MOFs are anticipated to serve as highly efficient mediums for gas separation, requiring minimal energy expenditure, based on their adsorption or gas breakthrough/diffusion properties.
