Porous Materials with 2D Building Units: Adsorption and Catalysis

About this Research Topic

Two-dimensional (2D) materials, including graphene, carbon nitride, transition metal carbides, among others, have large specific surface areas (SSAs) which make them attractive candidates in applications related to adsorption and heterogeneous catalysis. However, due to interactions such as hydrogen bonding and van der Waals forces, 2D materials when existing in bulk easily undergo layer-by-layer stacking and produce 3D materials (e.g., graphite, graphitic carbon nitride, etc.) with significantly reduced SSAs. In other words, large numbers of the adsorption and reaction sites on individual 2D materials become inaccessible and the adsorption capacity and reaction rate are decreased. Hence, it is necessary to develop strategies that are capable of either alleviating the layer-by-layer restacking or turning the 2D materials into porous 3D frameworks.

Although the soft- and hard-templating methods were initially invented for synthesizing porous silicas and carbons, they have recently been demonstrated to be applicable to graphene and carbon nitride materials by using appropriate precursors and templates. Furthermore, owing to the 2D structure chemical and physical activation processes that create in-plane pores have also been developed. These in-plane pores not only can render the materials with more adsorption and reaction centers, but also form additional passages for mass and charge transportation that are critical in energy conversion and storage technologies.

This Research Topic aims to explore strategies that help preserve the intrinsic large SSAs of 2D materials and make the most use of this property during their applications for adsorption and catalysis.

We invite submissions of Original Research, Review, Mini-review and Perspective articles related to the following topics:
• Development of porous 3D structures of 2D materials
• Development of 2D materials with in-plane pores
• Development of 2D-0D, 2D-1D and 2D-2D layer-by-layer composite materials with interlayer pores
• Porous 2D materials-based systems for gas adsorption and the recovery or immobilization of ions/molecules in liquids
• Porous 2D materials-based systems for heterogeneous catalysis.
