Abstract
Integrating the advantages of metal–organic framework (MOFs) and ionic organic polymers (iCOPs), we fabricated a series of novel hybrid materials (core–shell M@iCOPs) by growing iCOP shell layers of varying thicknesses on the NH2-UiO-66. These M@iCOP hybrids, with NH2-UiO-66 serving as an embedded “adsorption engine,” exhibit richer pore channels, which combined with the nitrogen-rich structure and π-π stacking interactions in the shell layer of the iCOPs, which led to a significant enhancement of CO2 adsorption with up to 3.33 mmol·g−1 at 0 °C and 1 bar. Remarkably, M@iCOPs-400, which possesses abundant ionic and Lewis acid sites, demonstrates excellent performance in CO2 conversion under milder conditions through interfacial synergistic effect, affording various cyclic carbonates in 90–99% yields. Overall, this research provides a straightforward and cost-effective approach for constructing core–shell M@iCOP materials.
期刊介绍:
Advanced Composites and Hybrid Materials is a leading international journal that promotes interdisciplinary collaboration among materials scientists, engineers, chemists, biologists, and physicists working on composites, including nanocomposites. Our aim is to facilitate rapid scientific communication in this field.
The journal publishes high-quality research on various aspects of composite materials, including materials design, surface and interface science/engineering, manufacturing, structure control, property design, device fabrication, and other applications. We also welcome simulation and modeling studies that are relevant to composites. Additionally, papers focusing on the relationship between fillers and the matrix are of particular interest.
Our scope includes polymer, metal, and ceramic matrices, with a special emphasis on reviews and meta-analyses related to materials selection. We cover a wide range of topics, including transport properties, strategies for controlling interfaces and composition distribution, bottom-up assembly of nanocomposites, highly porous and high-density composites, electronic structure design, materials synergisms, and thermoelectric materials.
Advanced Composites and Hybrid Materials follows a rigorous single-blind peer-review process to ensure the quality and integrity of the published work.
