- To provide a comparative analysis with traditional porous materials and outline future research directions.
Main Methods:
- Review of recent literature on the design and synthesis of HP-MOFs and their composites/derivatives.
- Analysis of structure-property relationships for diverse applications.
- Comparative assessment of HP-MOFs against conventional porous materials like zeolites and porous silica.
Main Results:
- HP-MOFs, composites, and derivatives demonstrate enhanced performance in catalysis, gas storage/separation, air filtration, sewage treatment, sensing, and energy storage.
- Hierarchical porosity facilitates improved diffusion and accessibility for larger species.
- Typical reports showcase the versatility and effectiveness of these advanced materials.
Conclusions:
