Mesh-like structure integrated core-shell-shell nanocomposites for enhanced stability and performance in carbon capture.

ABSTRACT: Carbon capture is essential for mitigating climate change, yet most sorbents struggle to combine high capacity with chemical stability. Here we report core-shell-shell (CSS) nanocomposites that integrate adsorption efficiency with exceptional robustness. The design couples a metal-organic framework (MOF) core, which enriches local CO₂ concentration, with a polyamine shell that is reorganized into a porous, ordered network through entanglement with an outer covalent organic framework (COF) shell. This hierarchical architecture enables dual amine functionalization via sequential "click" and Schiff-base reactions, achieving a CO₂ uptake of 3.4 mmol g^-1 at 1 bar. The COF outer layer also acts as a protective barrier, suppressing humidity interference and doubli
