Hierarchically Porous Metal-Organic Frameworks (HP‐MOFs): Synthesis and Applications

About this Research Topic

Metal-organic frameworks (MOFs) with high porosity have received significant attention as promising materials for many applications such as hydrogen storage, catalysis owing to their unique properties. However, to date, many of the reported MOFs have microporous structures, which slow down diffusion/mass transfer and limit the accessibility of bulkier molecules to their internal surface. Thus, developing an efficient way to create larger pores (i.e. mesopores and macropores) into microporous MOFs to form hierarchical porous metal-organic frameworks (HP-MOFs) is crucial. Change in pore size facilitates the diffusion and mass transfer of guest molecules, making HP-MOFs excellent candidates for various technological applications.

The unique properties of HP-MOFs such as pore size distribution, controlled morphology, customized functionality, etc. are key aspects of these materials that can be tuned to improve performance. Extending the pore size of MOFs is imperative to permit the diffusion of large size molecules into the porous structure of the host with high efficiency. Introducing more mesopores and macropores into conventionally microporous MOFs is a route to accelerating the reaction rate for diffusion/mass transfer limited processes, thus paving the way for various applications including bulky drug delivery, large molecule adsorption, separation, energy storage, and catalysis.

This Research Topic would like to draw attention to the importance of facile synthesis of new types of HP-MOFs with varied porosity and their potential new applications in less or unexplored research areas. The current Research Topic aims to build substantial research grounds that would benefit researchers working in the same field and other future researchers. Manuscripts to be submitted in this Research Topic would include full articles, communications, and review articles focusing on, but not limited to, the following areas:

• Generation of macro-porosity in microporous MOFs.

• Synthesis strategies with or without templates for HP-MOFs.

• Tuning of porosity in HP-MOFs.

• Morphology controlled synthesis of HP-MOFs.

• Applications of HP-MOFs in various fields including energy storage, catalysis (thermal, photo and electro), gas absorption, and separation and water treatment.


Keywords: Hierarchical porous structures, Metal organic frameworks, Morphology dependent activity, Environmental Remediation
