Advanced Functional Materials, Год журнала: 2023, Номер 33(45)

Опубликована: Авг. 27, 2023

Abstract Core–shell structures, where the “guest” material is encapsulated within a protective shell, integrate advantages of different materials to enhance overall properties composite. Covalent–organic frameworks (COFs) are favorable candidates for composing core–shell structures due their inherent porosity, good activity, excellent stability, and other advantages. In particular, COFs as shells encapsulate functional becoming increasingly popular in fields environmental remediation energy conversion. However, there lack reviews on COF‐based materials. this context, review provides systematic summary current research composites. First, simple classification made The second part describes main synthesis methods. changes brought about by COF shell composites applications photocatalysis, electrocatalysis, adsorption, sensing, supercapacitors then emphasized. Finally, new perspectives future development challenges presented. purpose study provide insights into design application

Highly Flexible and Self‐Standing Covalent Organic Framework–Metal–Organic Framework (COF–MOF) Composite Crystalline Porous Material (CPM) Membrane for Molecular Separation

Advanced Functional Materials, Год журнала: 2024, Номер 34(19)

Опубликована: Янв. 6, 2024

Abstract Crystalline porous materials (CPMs), including covalent organic frameworks (COFs) and metal–organic (MOFs), are promising for advanced separation technologies. However, the challenge of transforming nanoscale CPMs into large‐area functional membranes hinders their application in membrane process. Herein, a self‐standing pure COF (TpPa‐1) nanofiber with high crystallinity, good flexibility, excellent mechanical properties, scalability is prepared using an electrospinning process polymer sacrificial template strategy. Subsequently, innovatively used to replace traditional inorganic discs, metal meshes, as supports, COF–MOF composite CPM through tailorable confined growth zeolite imidazolium salt frame‐8 (ZIF‐8) on surface gaps nanofibers. The exhibits permeability significantly enhances selectivity dyes. Moreover, MOF form interpenetrating network structure, similar chemical properties improve interfacial stability between two phases, giving long‐term performance. This first molecular sieving performance, which provides new insights design high‐performance robust membranes.
