Metal–Organic Frameworks (MOFs)

Metal-organic frameworks are a class of highly ordered crystalline porous materials formed by metal ions or metal clusters as nodes 

and linked by organic ligands. Due to their ultra-high specific surface area, adjustable pore size structure, and highly designable 

chemical composition and surface functionalization capabilities, MOFs have shown a wide range of research and application 

potential in the fields of gas storage and separation, catalysis, sensing, biomedical materials, and energy storage.

(1) Gas storage and separation: MOFs excel in the field of gas adsorption and separation, especially in the storage and selective 

separation of hydrogen, methane and carbon dioxide. The adsorption performance is mainly affected by the specific surface area, 

pore volume, pore size distribution and gas-skeleton interaction strength. The results show that the adsorption heat and storage 

capacity of MOF's target gas can be significantly optimized by regulating the metal node and organic ligand structure. For example, 

MOFs like PCN-14 exhibit high methane storage capacity under medium and high pressure conditions, making them potentially valuable in natural gas storage and transportation.

(2) Catalysis and electrocatalysis: MOFs and their derivatives have received widespread attention in the field of catalysis. MOFs 

themselves can be used as single-point or multi-site catalytic platforms with well-defined structures, and their metal nodes, ligands 

and defect sites can participate in catalytic reactions. At the same time, MOFs are also important precursors for the preparation of 

porous carbon, metal/metal oxide composite catalysts. In terms of electrocatalysis, MOFs and MOF-derived materials have been 

used in systems such as hydrogen evolution (HER), oxygen evolution (OER), and oxygen reduction (ORR), where MOF-derived catalysts with polymetallic nodes or the introduction of heteroatoms usually exhibit better activity and stability. It should be pointed out that the conductivity of MOFs is usually low, and actual electrocatalytic applications often rely on structural regulation or derivatization strategies to improve their electrochemical properties.

(3) Biosensing and drug delivery: Due to their good pore structure controllability and functionalization characteristics, MOFs have 

also been widely studied in the field of biosensing and drug delivery. By introducing fluorescent probes, enzymes, or functional 

nanomaterials, MOFs can be used to detect and image biomolecules such as ATP, ions, or small molecule metabolites. In addition, 

some MOFs, such as ZIF-8, have controllable structural stability and pH-responsive behavior under physiological conditions, making 

them potential drug carrier materials. Most of the relevant research focuses on in vitro experiments and model systems, and their 

biosafety and long-term stability still need to be systematically evaluated.

(4) Energy storage and photothermal applications: MOFs and their derivatives also show research potential in the fields of 

supercapacitors, battery electrode materials, and photothermal conversion. By constructing multi-level pore structures or 

introducing conductive components, MOF-derived materials can achieve high specific capacitance and good cyclic stability. 

In the direction of photothermal diagnosis and treatment, MOFs are mainly used as functional carriers or composite components, 

and their practical application is still in the exploration stage.
