Special Issue Information

Dear Colleagues,

Organic‒inorganic hybrid materials with interpenetrating porosity, tunable chemical structures, and excellent performance have attracted tremendous attention. Recently, there has been increasing interest in delivering advanced organic‒inorganic hybrid materials for energy utilization and environmental remediation. It will focus on various organic‒inorganic hybrid materials including metal‒organic frameworks (MOFs), zeolitic‒imidazolate frameworks (ZIFs), mixed-matrix polymeric material, porous metal/metal oxide/graphene hybrid materials, and so on.

The conventional techniques of separation, such as the desalination of sea water, are highly energy-intensive. As an alternative, material separation is technically feasible and economically viable with the advantages of easy operation, low cost, and high efficiency. In these techniques, it is critically important to design and develop novel high-performance separation materials. Despite organic‒inorganic hybrid materials being up-and-coming candidates in separation applications, more synthesis strategies and microscopic mechanisms are required to investigate the promising organic‒inorganic hybrid materials with high efficiency and low cost for the energy and environmental fields.

This Special Issue will provide a comprehensive overview on recent advances in designing and advancing organic‒inorganic hybrid materials for gas separation, catalysis, thermal energy storage, etc. The selected articles will provide a state-of-the-art overview of the progress over the last years in the design, synthesis, characterization, simulation, and application of organic‒inorganic hybrid materials.

Potential topics include but are not limited to the following:

  • Development and characterization of new organic‒inorganic hybrid materials;
  • Calculation and simulation of the structure‒property relationships of organic‒inorganic hybrid materials;
  • Incorporation of different inorganic substances in the polymeric matrix, such as metal/metal oxide/sulfide/phosphide, graphene, etc.;
  • Studying the potential applications of organic‒inorganic hybrid materials;
  • Separation and purification of gases or liquids;
  • Storage of gases (H2, CO2, CH4, etc.);
  • Desalination of sea water;
  • Thermal energy storage;
  • Lithium battery material.

Due to their large surface area and pore volume, three-dimensional covalent organic frameworks (3D COFs) have emerged as competitive porous materials. However, structural dynamic behavior, often observed in imine-linked 3D COFs, could potentially unlock their potential application in gas storage. Herein, we showed how a pre-locked linker strategy introduces breaking dynamic behavior in 3D COFs. A predesigned planar linker-based 3,8-diamino-6-phenylphenanthridine (DPP) was prepared to produce non-dynamic 3D JUC-595, as the benzylideneamine moiety in DPP locked the linker flexibility and restricted the molecular bond rotation of the imine linkages. Upon solvent inclusion and release, the PXRD profile of JUC-595 remained intake, while JUC-594 with a flexible benzidine linker experienced crystal transformation due to framework contraction–expansion. As a result, the activated JUC-595 achieved higher surface areas (754 m2 g−1) than that of JUC-594 (548 m2 g−1). Furthermore, improved CO2 and CH4 storages were also seen in JUC-595 compared with JUC-594. Impressively, JUC-595 recorded a high normalized H2 storage capacity that surpassed other reported high-surface area 3D COFs. This works shows important insights on manipulating the structural properties of 3D COF to tune gas storage performance. Full article

The shape and topology of pores have significant impacts on the gas storage properties of nanoporous materials. Metal–organic frameworks (MOFs) are ideal materials with which to tailor to the needs of specific applications, due to properties such as their tunable structure and high specific surface area. It is, therefore, particularly important to develop descriptors that accurately identify the topological features of MOF pores. In this work, a topological data analysis method was used to develop a topological descriptor, based on the pore topology, which was combined with the Extreme Gradient Boosting (XGBoost) algorithm to predict the adsorption performance of MOFs for methane/ethane/propane. The final results show that this descriptor can accurately predict the performance of MOFs, and the introduction of the topological descriptor also significantly improves the accuracy of the model, resulting in an increase of up to 17.55% in the R2 value of the model and a decrease of up to 46.1% in the RMSE, compared to commonly used models that are based on the structural descriptor. The results of this study contribute to a deeper understanding of the relationship between the performance and structure of MOFs and provide useful guidelines and strategies for the design of high-performance separation materials.
