Metal organic framework (MOF) materials have attracted great attention due to their well-ordered and controllable pores possessing of prominent potentials for gas molecule sorption and separation performances. Organizing the MOF crystals to a continuous membrane with a certain scale will better exhibit their prominent potentials. Reports in recent years concentrate on well grown MOF membranes o...
Simulation of gas adsorption in flexible porous materials is still limited by the slow progress in the development of flexible force fields. Moreover, the high computational cost of such flexible force fields may be a drawback even when they are fully developed. In this work, molecular simulations of gas adsorption and diffusion of carbon dioxide and methane in NH2-MIL-53(Al) are carried out us...
Kinetic Modeling of Ring-Opening Polymerization of Benzoxazines Using MIL-53-Al as a Potent Catalyst
In this study, we report the successful synthesis of a novel Al-based MOF/polybenzoxazine nanocomposite by facile and green approach via thermally induced ring-opening polymerization (ROP). Structural thermal characterization synthesized was accomplished using FTIR, XRD, BET TGA, DSC techniques, respectively. The Al-MOF showed catalytic activity in ROP good stability compared to non-catalyzed s...
O solid-state NMR spectroscopy is employed to investigate the cation disorder in metal–organic frameworks containing two different types of metal cations. Although NMR offers exquisite sensitivity to the local, atomic-scale structure, making it an ideal tool for the characterisation of disordered materials, the low natural abundance of O (0.037%) necessitates expensive isotopic enrichment to ac...
